Predicted to enable several functions, including integrin binding activity; platelet-derived growth factor binding activity; and protease binding activity. Predicted to be an extracellular matrix structural constituent. Involved in response to mechanical stimulus and skeletal system development. Located in collagen-containing extracellular matrix. Biomarker of bladder neck obstruction; glomerulosclerosis; myocardial infarction; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome; Ehlers-Danlos syndrome hypermobility type; end stage renal disease; and vascular type Ehlers-Danlos syndrome. Orthologous to human COL3A1 (collagen type III alpha 1 chain). [provided by Alliance of Genome Resources, Apr 2022]
