Mitochondrial 70kDa heat shock protein (mtHsp70), also known as mortalin, is a protein that in humans is encoded by the HSPA9 gene.

Function

The product encoded by this gene belongs to the heat shock protein 70 family which contains both heat-inducible and constitutively expressed members. The latter are called heat-shock cognate proteins. This gene encodes a heat-shock cognate protein. This protein plays a role in the control of cell proliferation. It may also act as a chaperone.

Interactions

HSPA9 has been shown to interact with FGF1 and P53.
