Model organisms have been used in the study of SNAPC4 function. A conditional knockout mouse line, called Snapc4tm1a(KOMP)Wtsi[7][8] 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.[9][10][11]
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[5][12] 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.[5]
Interactions [link]
SNAPC4 has been shown to interact with SNAPC1,[13] POU2F1[1][14] and SNAPC2.[1][13]

Do you wanna play?
I say Hey! Snappy Kakkie!
I said whatcha' say!
The water she is nice we can steal away
They'll never know we're gone 'til the break 'o day
Come on! Come on!
I say Hey Snappy Kakkie
Did they talk to you today?
I say Hey Snappy Kakkie
Did you see it their way?
The moon she is high, we must leave tonite
We must get away, we will join the fight
Come on! Come on!
I say Hey Snappy Kakkie!
Did our brothers stay
I say Hey Snappy Kakkie
Will our sisters pay
Does it really matter of the friends we lost
It doesn't really matter cause their souls were lost
Come on! Come on!
