Previous GeneCards Identifiers for COL25A1 Gene
This gene encodes a brain-specific membrane associated collagen. A product of proteolytic processing of the encoded protein, CLAC (collagenous Alzheimer amyloid plaque component), binds to amyloid beta-peptides found in Alzheimer amyloid plaques but CLAC inhibits rather than facilitates amyloid fibril elongation (PMID: 16300410). A study of over-expression of this collagen in mice, however, found changes in pathology and behavior suggesting that the encoded protein may promote amyloid plaque formation (PMID: 19548013). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]
GeneCards Summary for COL25A1 Gene
COL25A1 (Collagen, Type XXV, Alpha 1) is a Protein Coding gene. Diseases associated with COL25A1 include fibrosis of extraocular muscles, congenital, 5 and ataxia, cerebellar, cayman type. Among its related pathways are Phospholipase-C Pathway and ERK Signaling. GO annotations related to this gene include heparin binding and beta-amyloid binding. An important paralog of this gene is COL21A1.
UniProtKB/Swiss-Prot for COL25A1 Gene
Inhibits fibrillization of beta amyloid peptide during the elongation phase. Has also been shown to assemble amyloid fibrils into protease-resistant aggregates. Binds heparin.
