Protein Name: Heat shock protein HSP 90-beta

UniprotKB/SwissProt ID: HS90B_HUMAN (P08238)

Gene Name: HSP90AB1

Synonyms: HSP90B, HSPC2, HSPCB

Organism: Homo sapiens (Human).

Function: Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
