SEC24 family, member A (S. cerevisiae) is a protein that in humans is encoded by the SEC24A gene.[1] The protein belongs to a protein family that are homologous to yeast Sec24.[2] It is a component of coat protein II (COPII)-coated vesicles that mediate protein transport from the endoplasmic reticulum.[1]

Model organisms

Model organisms have been used in the study of SEC24A function. A conditional knockout mouse line, called Sec24atm1a(KOMP)Wtsi[8][9] 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.[10][11][12]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[6][13] Twenty five tests were carried out on mutant mice and one significant abnormality was observed.[6] Male homozygotes had decreased circulating cholesterol and LDL cholesterol levels.[6]
