|Protein Name||DnaJ (Hsp40) homolog, subfamily B, member 2|
|Ref Sequence Id||NP_001029764.1|
|Amino Acid Lenth||278|
|Protein Existence Status||Unreviewed: Experimental evidence at transcript level|
|Protein Function||DnaJ proteins, also known as heat shock protein 40 (Hsp40 or Hsc40) act as cochaperones to the molecular chaperone DnaK (Hsp70), which is responsible for several cellular processes such as rescuing misfolded proteins, folding polypeptide chains, transport of polypeptides through membranes, assembly and disassembly of protein complexes, and control of regulatory proteins; primarily facilitates the hydrolysis of ATP from DnaK that is necessary for the chaperone activity of DnaK; DNAJA1 appears to be involved in importing proteins into the mitochondria|
