Predicted to be an extracellular matrix structural constituent conferring tensile strength. Acts upstream of or within several processes, including collagen fibril organization; homeostasis of number of cells within a tissue; and regulation of cell growth involved in cardiac muscle cell development. Located in interstitial matrix. Is expressed in several structures, including cranium; genitourinary system; gut; heart and pericardium; and skeletal musculature. Orthologous to human COL14A1 (collagen type XIV alpha 1 chain). [provided by Alliance of Genome Resources, Apr 2022]
