Model organisms have been used in the study of SNAPC4 function. A conditional knockout mouse line, called Snapc4^{tm1a(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 — at the Wellcome Trust Sanger Institute.[13][14][15]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[9][16] Twenty six tests were carried out on mutant mice and two significant abnormalities were observed. No homozygous mutant embryos were recorded during gestation and, in a separate study, no homozygous animals were observed at weaning. The remaining tests were carried out on adult heterozygous mutant animals and no further abnormalities were observed.[9]

Interactions

SNAPC4 has been shown to interact with SNAPC1,[17] POU2F1[5][18] and SNAPC2.[5][17]
