Recombinant Human Inositol 1,4,5-trisphosphate receptor type 2 (ITPR2), Truncated

Uniprot Id

Q14571

Target Species

Human

Target Name

ITPR2

Target Full Name

Inositol 1,4,5-trisphosphate-gated calcium channel ITPR2

Target Function

Receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. This release is regulated by cAMP both dependently and independently of PKA.

Target Involvement

Anhidrosis, isolated, with normal sweat glands (ANHD)

Target Subcellular Location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Target Protein Families

InsP3 receptor family

Target Tissue Specificity

Isoform Short is found in skeletal muscle and heart.

Target Synonyms

4; 5-trisphosphate receptor; Inositol 1 4 5 trisphosphate receptor type 2; Inositol 1,4,5-trisphosphate receptor type 2; Inositol 145 trisphosphate receptor type 2; InsP3 R2; InsP3R2; IP3 R2; IP3 receptor; IP3 receptor isoform 2; IP3R 2; IP3R2; ITPR 2; Itpr2; ITPR2_HUMAN; Type 2 inositol 1 4 5 trisphosphate receptor; Type 2 inositol 1; Type 2 inositol 145 trisphosphate receptor; Type 2 InsP3 receptor

Target Background

The protein encoded by this gene belongs to the inositol 1, 4, 5-triphosphate receptor family, whose members are second messenger intracellular calcium release channels. These proteins mediate a rise in cytoplasmic calcium in response to receptor activated production of inositol triphosphate. Inositol triphosphate receptor-mediated signaling is involved in many processes including cell migration, cell division, smooth muscle contraction, and neuronal signaling. This protein is a type 2 receptor that consists of a cytoplasmic amino-terminus that binds inositol triphosphate, six membrane-spanning helices that contribute to the ion pore, and a short cytoplasmic carboxy-terminus. A mutation in this gene has been associated with anhidrosis, suggesting that intracellular calcium release mediated by this protein is required for eccrine sweat production.
