ARHGDIA [ENSP00000269321]
 
Rho GDP dissociation inhibitor (GDI) alpha; Regulates the GDP/GTP exchange reaction of the Rho proteins by inhibiting the dissociation of GDP from them, and the subsequent binding of GTP to them (By similarity)
CDKN1B [ENSP00000228872]
 
cyclin-dependent kinase inhibitor 1B (p27, Kip1); Important regulator of cell cycle progression. Involved in G1 arrest. Potent inhibitor of cyclin E- and cyclin A-CDK2 complexes. Positive regulator of cyclin D-dependent kinases such as CDK4. Regulated by phosphorylation and degradation events
