Dnaja3 - DnaJ heat shock protein family (Hsp40) member A3

Enables GTPase regulator activity; receptor tyrosine kinase binding activity; and unfolded protein binding activity. Involved in skeletal muscle acetylcholine-gated channel clustering. Acts upstream of or within several processes, including activation-induced cell death of T cells; mitochondrial DNA replication; and positive regulation of T cell proliferation. Located in several cellular components, including mitochondrion; neuromuscular junction; and postsynaptic membrane. Is extrinsic component of plasma membrane. Orthologous to human DNAJA3 (DnaJ heat shock protein family (Hsp40) member A3). [provided by Alliance of Genome Resources, Apr 2022]
