Overview
COL18A1 COLA18A probably plays a major role in determining the retinal structure as well as in the closure of the neural tube. Defects in COL18A1 are a cause of Knobloch syndrome type 1 (KNO1). An autosomal recessive disorder defined by the occurrence of high myopia, vitreoretinal degeneration with retinal detachment, macular abnormalities and occipital encephalocele. Belongs to the multiplexin collagen family. 3 isoforms of the human protein are produced by alternative promoter. Note: This description may include information from UniProtKB.
Protein type: Secreted, signal peptide; Secreted
Chromosomal Location of Human Ortholog: 21q22.3
Cellular Component: extracellular matrix; extracellular space; collagen; endoplasmic reticulum lumen; extracellular region; basement membrane
Molecular Function: identical protein binding; protein binding; metal ion binding; structural molecule activity
Biological Process: response to drug; collagen catabolic process; negative regulation of cell proliferation; extracellular matrix disassembly; extracellular matrix organization and biogenesis; organ morphogenesis; visual perception; positive regulation of cell proliferation; endothelial cell morphogenesis; angiogenesis; cell adhesion; response to hydrostatic pressure; positive regulation of cell migration
