basic FUNCTION	involved in the maturation of 20S proteasomes
	is a proteaseome assembly chaperone that dimerizes with PSMG1, to form the PSMG1/PSMG2 complex

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

a component

heterodimer PSMG1 and PSMG2

INTERACTION

DNA

RNA

small molecule

protein

cytoplasmic mutant TARDBP interacts with proteasome assembly proteins PSMG2, which might lead to the impairment of the proteasomal activity
