General annotation (Comments)

Function

Type II collagen is specific for cartilaginous tissues. It is essential for the normal embryonic development of the skeleton, for linear growth and for the ability of cartilage to resist compressive forces By similarity.

Subunit structure

Homotrimers of alpha 1(II) chains By similarity.

Subcellular location

Secretedextracellular spaceextracellular matrix By similarity.

Developmental stage

Initially, the transcripts are localized to notochord, somites, and the dorsal region of the lateral plate mesoderm. At later stages of development and parallel to increased mRNA accumulation, collagen expression becomes progressively more confined to chondrogenic regions of the tadpole. Ref.1

Domain

The C-terminal propeptide, also known as COLFI domain, have crucial roles in tissue growth and repair by controlling both the intracellular assembly of procollagen molecules and the extracellular assembly of collagen fibrils. It binds a calcium ion which is essential for its function By similarity.

Post-translational modification

Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains By similarity.

Sequence similarities

Belongs to the fibrillar collagen family.

Contains 1 fibrillar collagen NC1 domain.

Contains 1 VWFC domain.
