PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	four ANK repeats in the N-terminal part of the protein might have evolved to ensure a more elaborate or more refined substrate recognition, to mediate the interaction with as yet unknown protein partners, or even to support a putative chaperone function
	first 92 AAs are predicted to encode a mitochondrial targeting sequence
	two AAA+ modules, that bind and hydrolyze ATP and construct the core of the hexameric ring
	a specific C-terminal D2 domain, which is typical for AAA+ proteins involved in polypeptide chain threading through the hexamer central channel

mono polymer

homomer , hexamer

HOMOLOGY

interspecies	homolog to murine Clpb
	ortholog to rattus Skd3

Homologene

FAMILY	clpA/clpB family
	AAA+ protein family

CATEGORY

chaperone/stress , enzyme , regulatory

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,mitochondria

basic FUNCTION	may function as a regulatory ATPase and be related to secretion/protein trafficking process
	protect cells from the devastating effects of protein inactivation and aggregation that arise after extreme heat stress
	can passively thread soluble denatured proteins
	CLPB hexamers remain associated during several ATP hydrolysis events required to partially or completely translocate substrates through the protein central channel, and CLPB dynamics is tuned by DnaK and substrate proteins
	its function might be related to apoptosis
	key role of CLPB in regulating protein folding inside the mitochondrial matrix

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

exocytosis transport , cellular trafficking transport

PATHWAY

metabolism

signaling

a component

forms a hexameric, ring-shaped complex that functions as a tightly regulated, ATP-powered molecular disaggregation machine

INTERACTION
