Summary: Predicted to enable collagen binding activity. Acts upstream of or within neuron apoptotic process; phosphatidylinositol 3-kinase/protein kinase B signal transduction; and response to UV. Located in extracellular matrix and sarcolemma. Is expressed in several structures, including cardiovascular system; central nervous system; extraembryonic component; gut; and reproductive system. Human ortholog(s) of this gene implicated in Bethlem myopathy and Ullrich congenital muscular dystrophy 1B. Orthologous to human COL6A2 (collagen type VI alpha 2 chain).

What's a GeneRIF?

Collagen VIalpha2 chain deficiency causes trabecular bone loss by potentially promoting osteoclast differentiation through enhanced TNFalpha signaling.
Title: Collagen VIα2 chain deficiency causes trabecular bone loss by potentially promoting osteoclast differentiation through enhanced TNFα signaling.
gamma-sarcoglycan-null/Col6a2Deltaex5 (Col6a2 deficient) mice exhibit reduced muscle pathology compared with gamma-sarcoglycan-null mice. Specifically, fewer muscle fibers are degenerating, fiber size varies less. Surprisingly, in spite of this reduction in muscle pathology, muscle function is not significantly improved.
Title: Collagen VI deficiency reduces muscle pathology, but does not improve muscle function, in the γ-sarcoglycan-null mouse.

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.
