Syntaxin-8 is a protein that in humans is encoded by the STX8 gene.[1][2][3] Syntaxin 8 directly interacts with HECTd3 and has similar subcellular localization.[4] The protein has been shown to form the SNARE complex with syntaxin 7, vti1b and endobrevin. These function as the machinery for the homotypic fusion of late endosomes.[5]

Model organisms

Model organisms have been used in the study of STX8 function. A conditional knockout mouse line, called Stx8tm2a(EUCOMM)Wtsi[10][11] 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.[12][13][14] Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[8][15] Twenty four tests were carried out on homozygous mutant adult mice, however no significant abnormalities were observed.[8]

Interactions

STX8 has been shown to interact with Vesicle-associated membrane protein 8,[16] VTI1B[17][18] and STX7.[16]
