Summary: Predicted to enable identical protein binding activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Acts upstream of or within several processes, including endothelial cell morphogenesis; positive regulation of endothelial cell apoptotic process; and positive regulation of vascular endothelial cell proliferation. Located in basement membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Used to study pigment dispersion syndrome. Human ortholog(s) of this gene implicated in primary angle-closure glaucoma. Orthologous to human COL18A1 (collagen type XVIII alpha 1 chain).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
