HOMOLOGY

Homologene

FAMILY

CATEGORY

regulatory

SUBCELLULAR LOCALIZATION

basic FUNCTION	inhibits neuronal differentiation via RhoA and Citron kinase (Berto 2007)
	polyubiquitin binding protein involved in NF-kappaB signaling (Fenner 2009)

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

TTC3-RhoA-CIT-K pathway that could be a crucial determinant of neuronal development, whose hyperactivity may result in detrimental effects on the normal differentiation program (Berto 2007)

a component

INTERACTION

DNA

RNA

small molecule

protein

interacts with Citron kinase (CIT-K) and Citron N (CIT-N), two effectors of the RhoA small GTPase that have previously been involved in neuronal proliferation and differentiation (Berto 2007)
