CATEGORY

structural protein

SUBCELLULAR LOCALIZATION	extracellular
text	extracellular matrix

basic FUNCTION	maintaining the integrity of ECM containing COLI fibers
	may be involved in basement membrane regulation providing specific molecular bridges between fibrils and other matrix components (Thierry 2004)
	with COL14A1, might well be able to serve different functions during human embryonic development although their structures are highly similar (Thierry 2004)

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

development

text	skeletal development

PATHWAY

metabolism

signaling

a component

constituent of fibril associated collagen with interrupted triple helices (FACIT)

INTERACTION

DNA

RNA

small molecule

protein	COLI fibers
	COMP binds to COL12A1 and COL14A1 via their C-terminal collagenous domains, and three proteins codistribute in a characteristic narrow zone in the superficial papillary dermis of healthy human skin
