Summary: Predicted to enable identical protein binding activity; platelet-derived growth factor binding activity; and protease binding activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Involved in several processes, including cellular response to epidermal growth factor stimulus; cellular response to mechanical stimulus; and cellular response to vitamin E. Acts upstream of or within collagen-activated tyrosine kinase receptor signaling pathway. Located in extracellular space and secretory granule. Used to study cholestasis and metabolic dysfunction-associated steatotic liver disease. Biomarker of several diseases, including artery disease (multiple); bladder neck obstruction; liver disease (multiple); rheumatic heart disease; and ureteral obstruction. Human ortholog(s) of this gene implicated in several diseases, including Ehlers-Danlos syndrome arthrochalasia type 1; aggressive periodontitis; bone disease (multiple); cutaneous leishmaniasis; and dentinogenesis imperfecta. Orthologous to human COL1A1 (collagen type I alpha 1 chain). [provided by Alliance of Genome Resources, Apr 2025]

In vitro analysis using LX2 HSC cells indicated that ATII can augment TGFbeta1 and collagen type I alpha1 mRNA expression via periostin expression, suggesting that the interaction between ATII and periostin may serve a role in liver fibrosis development. In conclusion, blockade of ATIIinduced periostin may suppress the progression of liver fibrosis development.

Brefeldin A induced a significant up-regulation of Col1a1 mRNA levels in CFSC-2G hepatic stellate cells that was time-dependent. The UPR correlated with enhanced mRNA and protein levels of collagen type I in these cells. Analysis of the 3 branches of UPR revealed the activation of IRE1alpha, PERK and ATF6 in response to BFA. An IRE1alpha-p38 MAPK-Smad pathway may be responsible for the fibrogenic action of BFA on HSC.
Title: Unfolded protein response induced by Brefeldin A increases collagen type I levels in hepatic stellate cells through an IRE1α, p38 MAPK and Smad-dependent pathway.

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.
