Protein attributes

Sequence length	14 AA.
Sequence status	Fragment.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

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.
Subunit structure	Homotrimers of alpha 1(II) chains.
Subcellular location	Secreted › extracellular space › extracellular matrix 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.
Miscellaneous	These protein fragments where extracted from a 68 million years old fossil. The tryptic peptides required multiple purification steps in order to eliminate contaminants and to increase the concentration of peptidic material.
Sequence similarities	Belongs to the fibrillar collagen family. Contains 1 VWFC domain.
