Protein attributes

Sequence length	705 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in cell cycle control and signal transduction such as CNA2. Undergoes a functional cycle that is linked to its ATPase activity By similarity. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. Required for growth at high temperatures. Ref.6
Subunit structure	Interacts with the co-chaperone SGT1. Interacts directly with the substrate CNA2. Interacts with NAP1. Ref.6 Ref.8 Ref.15
Subcellular location	Cytoplasm. Mitochondrion Ref.9 Ref.11.
Induction	Expressed constitutively at a high level and is moderately induced by high temperatures dependent on transcription factor HSF1. Ref.1 Ref.5
Domain	The TPR repeat-binding motif mediates interaction with TPR repeat-containing proteins By similarity.
Miscellaneous	Present with 132053 molecules/cell in log phase SD medium. Ref.10
Sequence similarities	Belongs to the heat shock protein 90 family.
