Summary: Predicted to enable carbohydrate binding activity and protein homodimerization activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Acts upstream of or within chondrocyte proliferation; growth plate cartilage development; and tissue homeostasis. Predicted to be located in extracellular region. Predicted to be part of collagen type IX trimer. Predicted to be active in collagen-containing extracellular matrix and extracellular space. Is expressed in several structures, including genitourinary system; respiratory system; salivary gland primordium; sensory organ; and skeletal system. Used to study osteoarthritis. Human ortholog(s) of this gene implicated in Stickler syndrome; multiple epiphyseal dysplasia 6; and osteochondrodysplasia. Orthologous to human COL9A1 (collagen type IX alpha 1 chain).

Collagen IX deficiency leads to premature vascularization and ossification of murine femoral heads through an imbalance of pro- and antiangiogenic factors.
Title: Collagen IX deficiency leads to premature vascularization and ossification of murine femoral heads through an imbalance of pro- and antiangiogenic factors.
An accelerated hypertrophic differentiation caused by a disturbed Ihh-PTHrP signaling pathway may lead to a higher bone mineral density in the vertebral bodies of newborn Col IX -/- mice and, as a result, to the early onset of disc degeneration.
Title: Absence of collagen IX accelerates hypertrophic differentiation in the embryonic mouse spine through a disturbance of the Ihh-PTHrP feedback loop.
Results show that absence of Col IX induces early developmental, structural and biomechanical alterations in both vertebral body and intervertebral disc which eventually cause severe degenerative changes in the aging spine.
Title: Early changes in morphology, bone mineral density and matrix composition of vertebrae lead to disc degeneration in aged collagen IX -/- mice.

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.

Status: VALIDATED

Description

Transcript Variant: This variant (2) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at an alternate start codon, compared to variant 1. The encoded protein (isoform 2) has a shorter and distinct N-terminus, compared to isoform 1.
