Synaptotagmin-like protein 1 is a protein that in humans is encoded by the SYTL1 gene.[1][2]

Model organisms

Model organisms have been used in the study of SYTL1 function. A conditional knockout mouse line, called Sytl1tm1a(KOMP)Wtsi[11][12] 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.[13][14][15]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[9][16] Twenty four tests were carried out on homozygous mutant mice and six significant abnormalities were observed.[9] Females had abnormal locomotor coordination, caudal vertebral transformation, decreased circulating amylase levels and increased mean platelet volume. Both sexes displayed decreased IgG2b levels and abnormal peripheral blood lymphocyte parameters.[9]


SYTL1 has been shown to interact with RAB27A.[17][18][19]
