Function

Inositol 1,4,5-trisphosphate-gated calcium channel that upon inositol 1,4,5-trisphosphate binding transports calcium from the endoplasmic reticulum lumen to cytoplasm (PubMed:25329695). Exists in two states; a long-lived closed state where the channel is essentially 'parked' with only very rare visits to an open state and that ligands facilitate the transition from the 'parked' state into a 'drive' mode represented by periods of bursting activity (By similarity).

Involvement in disease

Anhidrosis, isolated, with normal sweat glands

ANHD

An autosomal recessive disorder characterized by generalized, isolated anhidrosis, severe heat intolerance, and morphologically normal eccrine sweat glands. Body growth, teeth, hair, nails, and skin are normal.

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

Phosphorylation by cAMP-dependent PKA on Ser-937 increases calcium release.

Phosphorylation by CaMK2 on Ser-150 significantly decreases the channel open probability.

Sequence similarities

Belongs to the InsP3 receptor family.

Tissue specificity

Isoform Short

Found in skeletal muscle and heart.

Cellular localization

  • Endoplasmic reticulum membrane
