LIMP2 has recently been identified as a novel component of [[intercalated disc]]s in [[cardiac muscle]]. [[Intercalated disc]]s are composed of [[gap junction]]s, [[adherens junction]]s and [[desmosome]]s, and are critical for the mechanical and electrical coupling of adjacent [[cardiomyocytes]]. The discovery of LIMP-2 as a component of this complex came about from a genetic screen of a homozygous, [[hypertension|hypertensive]] [[transgenic]] rat model of [[renin]] overexpression, in which a population of these rats rapidly develop [[heart failure]] and another remains compensated.<ref>{{cite journal | vauthors = Schroen B, Heymans S, Sharma U, Blankesteijn WM, Pokharel S, Cleutjens JP, Porter JG, Evelo CT, Duisters R, van Leeuwen RE, Janssen BJ, Debets JJ, Smits JF, Daemen MJ, Crijns HJ, Bornstein P, Pinto YM | title = Thrombospondin-2 is essential for myocardial matrix integrity: increased expression identifies failure-prone cardiac hypertrophy | journal = Circulation Research | volume = 95 | issue = 5 | pages = 515–22 | date = Sep 2004 | pmid = 15284191 | doi = 10.1161/01.RES.0000141019.20332.3e }}</ref> Out of 143 differentially-regulated genes, LIMP-2 was identified to be significantly upregulated in [[heart failure]]-prone rat [[cardiac muscle]] biopsies, which also proved true in human [[heart failure]]. Further analysis employing a LIMP-2 knockout mouse demonstrated that animals lacking LIMP-2 failed to flight a normal [[cardiac hypertrophy|hypertrophic]] response following [[Angiotensin II]] treatment, however they developed interstitial [[fibrosis]] and [[dilated cardiomyopathy]] coordinate with disrupted [[intercalated disc]] structure. Biochemical and [[immunohistochemistry|immunohistochemical]] analyses discovered that LIMP-2 [[protein-protein interaction|interacts]] with [[CDH2|N-cadherin]] at [[intercalated disc]]s, a function outside of [[lysosome|lysosomal]] membranes. Knockdown of LIMP-2 with [[RNA interference]] decreased the binding of [[CDH2|N-cadherin]] to the [[phosphorylation|phosphorylated]] form of [[CTNNB1|beta-catenin]], and LIMP-2 overexpression had the reverse effect.<ref name="ReferenceB">{{cite journal | vauthors = Schroen B, Leenders JJ, van Erk A, Bertrand AT, van Loon M, van Leeuwen RE, Kubben N, Duisters RF, Schellings MW, Janssen BJ, Debets JJ, Schwake M, Høydal MA, Heymans S, Saftig P, Pinto YM | title = Lysosomal integral membrane protein 2 is a novel component of the cardiac intercalated disc and vital for load-induced cardiac myocyte hypertrophy | journal = The Journal of Experimental Medicine | volume = 204 | issue = 5 | pages = 1227–35 | date = May 2007 | pmid = 17485520 | doi = 10.1084/jem.20070145 | pmc=2118572}}</ref>

Lysosome membrane protein 2 (LIMP-2) is a protein that in humans is encoded by the SCARB2 gene.[1] LIMP-2 is expressed in brain, heart, liver, lung and kidney, mainly in the membrane of lysosome organelles; however, in cardiac muscle, LIMP-2 is also expressed at intercalated discs. LIMP-2 in a membrane protein in lysosomes that functions to regulate lysosomal/endosomal transport. Mutations in LIMP-2 have been shown to cause Gaucher disease, myoclonic epilepsy, and action myoclonus renal failure syndrome. Abnormal levels of LIMP-2 have also been found in patients with hypertrophic cardiomyopathy.

Structure

Human LIMP-2 has a theoretical molecular weight of 54.3 kDa and is 478 amino acids in length.[2]

Though LIMP-2 was initially discovered in 1985 by Lewis et al. from rat liver lysosomes,[3] LIMP-2 was cloned in 1992 by two groups, one isolated LIMP-2 from human metastatic pancreatic islet tumor cells, and one from rat liver lysosomal membranes.[4][5] LIMP-2 was isolated as a protein of approximate molecular weight 85 kDa, synthesized from a precursor oform of approximately 77 kDa. The weight discrepancy between its theoretical (54.3 kDa) and observed (85 kDa) is due to the presence of 10 high mannose-type N-linked oligosaccharide chains in the human form of this protein, compared to 11 in mouse and rat.[6] LIMP-2 has two hydrophobic regions, one near the N-terminus and one near the C-terminus, as well as a short isoleucine/leucine-rich cytoplasmic tail consisting of 20 amino acids that serves as the lysosomal targeting sequence.[7][8] LIMP-2 has been shown to be expressed in brain, heart, liver, lung and kidney.[6]

Function

The protein encoded by this gene is a type III glycoprotein that is located primarily in limiting membranes of lysosomes and endosomes. Studies of the similar protein in mice and rat suggested that this protein may participate in membrane transportation and the reorganization of endosomal/lysosomal compartment.[9] In rat hepatic cells, LIMP-2 exhibited a half-life for internalization and lysosomal transport of 32 min and 2.0 h, respectively, which resembled that of well-known lysosomal proteins, lamp-1 and lamp-2, albeit different amino acid sequences in their cytoplasmic tails.[10]

LIMP2 has recently been identified as a novel component of intercalated discs in cardiac muscle. Intercalated discs are composed of gap junctions, adherens junctions and desmosomes, and are critical for the mechanical and electrical coupling of adjacent cardiomyocytes. The discovery of LIMP-2 as a component of this complex came about from a genetic screen of a homozygous, hypertensive transgenic rat model of renin overexpression, in which a population of these rats rapidly develop heart failure and another remains compensated.[11] Out of 143 differentially-regulated genes, LIMP-2 was identified to be significantly upregulated in heart failure-prone rat cardiac muscle biopsies, which also proved true in human heart failure. Further analysis employing a LIMP-2 knockout mouse demonstrated that animals lacking LIMP-2 failed to flight a normal hypertrophic response following Angiotensin II treatment, however they developed interstitial fibrosis and dilated cardiomyopathy coordinate with disrupted intercalated disc structure. Biochemical and immunohistochemical analyses discovered that LIMP-2 interacts with N-cadherin at intercalated discs, a function outside of lysosomal membranes. Knockdown of LIMP-2 with RNA interference decreased the binding of N-cadherin to the phosphorylated form of beta-catenin, and LIMP-2 overexpression had the reverse effect.[12]

LIMP-2 plays other roles in other organs. Characteristic tubular proteinuria observed in LIMP-2 knockout mice has been shown to be due to a failure of in lysosomal/endosomal fusion, thus proteins reabsorbed in the proximal tubule of the kidney are not properly proteolyzed, causing the proteinuria.[13] Deficiency of LIMP-2 in mice was also reported to impair cell membrane transport processes and cause pelvic junction obstruction, deafness, and peripheral neuropathy.[14]

Clinical significance

In patients with hypertrophic cardiomyopathy due to aortic stenosis, SCARB2 mRNA is significantly upregulated, suggesting that LIMP-2 may act as a hypertrophic marker.[12]

Mutations in SCARB2 have been shown to cause action myoclonus renal failure syndrome, a rare syndrome characterized by progressive neurological disease and associated with proteinuria, kidney failure, and Focal segmental glomerulosclerosis.[15][16][17]

Mutations in SCARB2 have also been shown to cause Gaucher disease and myoclonic epilepsy,[18] as LIMP-2 is critical for the proper sorting and targeting of glucocerebrosidase enzyme (the enzyme deficient in Gaucher disease) to lysosomes.

SCARB2 is a receptor for two viruses that cause hand, foot, and mouth disease in children, Enterovirus 71 and Coxsackievirus A16.[19]

Interactions

LIMP-2 has been shown to interact with:
