Annexin A6 is a protein that in humans is encoded by the ANXA6 gene.[1]

Function

Annexin VI belongs to a family of calcium-dependent membrane and phospholipid binding proteins. Although their functions are still not clearly defined, several members of the annexin family have been implicated in membrane-related events along exocytotic and endocytotic pathways. The annexin VI gene is approximately 60 kbp long and contains 26 exons. It encodes a protein of about 68 kDa that consists of eight 68-amino acid repeats separated by linking sequences of variable lengths. It is highly similar to human annexins I and II sequences, each of which contain four such repeats. Exon 21 of annexin VI is alternatively spliced, giving rise to two isoforms that differ by a 6-amino acid insertion at the start of the seventh repeat. Annexin VI has been implicated in mediating the endosome aggregation and vesicle fusion in secreting epithelia during exocytosis.[2]

Model organisms

Model organisms have been used in the study of ANXA6 function. A conditional knockout mouse line, called Anxa6tm1a(EUCOMM)Wtsi[9][10] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[11][12][13]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[7][14] Twenty six tests were carried out on mutant mice and one significant abnormality was observed: female homozygous mutant animals had an increased susceptibility to Citrobacter infection.[7]

Interactions

ANXA6 has been shown to interact with RAS p21 protein activator 1.[15]
