HighlightsIntroduction of STX7
STX7 is a protein that in humans is encoded by the STX7 gene. In melanocytic cells, STX7 gene expression may be regulated by MITF. STX7 is expressed in normal melanocytes, various benign melanocytic nevi, atypical nevi, and malignant melanoma. N-terminal regions of syntaxin 7, syntaxin 8, and vti1b contain well folded α-helical domains. Multidimensional NMR spectroscopy revealed that in syntaxin 7 and vti1b, the domains form three-helix bundles resembling those of syntaxin 1, Sso1p, and Vam3p.

The human syntaxin family consists of 15 proteins which are key molecules involved in the formation of transport vesicles in the exocytotic and endocytotic pathways. Published studies on the precise location of STX7 showed inconsistent results, where some studies suggested STX7 was associated with early endosomes, whereas others concluded that it resided in compartments within the late endosomal/lysosomal system. STX7 is required for the fusion of late endosomes with lysosomes, suggesting a role of STX7 as a regulator of membrane vesicular trafficking between late endosomes and lysosomes. STX7 has also been shown to be involved in the intracellular vacuolation process induced by the Helicobacter pylori-produced cytotoxin VacA in gastric epithelial cells. The expression level of STX7 protein is negatively related to tumor stage, suggesting that reduced expression of STX7 is associated with more aggressive tumors.

This research investigated the biogenesis pathway of HCV-induced autophagosomes. Results showed that HCV-induced phagocytes derived from the endoplasmic reticulum and underwent homotypic fusion to produce autophagosomes.
This study suggested that STX7 is a potential marker for distinguishing between normal B precursors (hematogones) and B lymphoblasts.
Authors conducted this research is to investigate the role of Stx7 in the release of lytic granules from cytotoxic T lymphocytes (CTLs). Results showed that the accumulation of recycling TCRs at the immunological synapse was associated with Stx7.
This research implied that aggressive tumors were related to the reduced expression of STX7.
This study indicated that Stx7 expression mediated by CSF-1 played a role in macrophage effector.
