Restin
This gene encodes the alpha chain of type XV collagen, a member of the FACIT collagen family (fibril-associated collagens with interrupted helices). Type XV collagen has a wide tissue distribution but the strongest expression is localized to basement membrane zones so it may function to adhere basement membranes to underlying connective tissue stroma. The proteolytically produced C-terminal fragment of type XV collagen is restin, a potentially antiangiogenic protein that is closely related to endostatin. Mouse studies have shown that collagen XV deficiency is associated with muscle and microvessel deterioration. [provided by RefSeq, May 2013]
Forensic Context
A study in humans demonstrated that the COL15A1 is significantly up-regulated in thermally injured skin compared to normal skin, indicating its role in the cell adhesion and extracellular matrix response during early wound repair [Greco et al. DOI:10.1016/j.burns.2009.06.211]. In mice selectively bred for differential methamphetamine consumption, the COL15A1 was overexpressed in the ventral midbrain of the low-drinking line, suggesting a potential association with extracellular matrix composition in brain reward circuitry related to addiction risk [Hitzemann et al. DOI:10.3390/brainsci9070155].
