pfam10393: Matrilin_ccoil (this model, PSSM-Id:287378 is obsolete and has been replaced by 463070)
Trimeric coiled-coil oligomerization domain of matrilin
This short domain is a coiled coil structure and has a single cysteine residue at the start which is likely to form a di-sulfide bridge with a corresponding cysteine in an upstream EGF (pfam00008) domain thereby spanning a VWA (pfam00092) domain. All three domains can be associated together as in the cartilage matrix protein matrilin, where this domain is likely to be responsible for oligomerization.
