Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| comment | FUNCTION Regulatory subunit of calcineurin, a calcium-dependent, calmodulin stimulated protein phosphatase. Confers calcium sensitivity.SUBUNIT Forms a complex composed of a calmodulin-dependent catalytic subunit (also known as calcineurin A) and a regulatory Ca(2+)-binding subunit (also known as calcineurin B) (PubMed:24018048). There are three catalytic subunits, each encoded by a separate gene (PPP3CA, PPP3CB, and PPP3CC) and two regulatory subunits which are also encoded by separate genes (PPP3R1 and PPP3R2). The regulatory subunit confers calcium sensitivity. Interacts with catalytic subunit PPP3CA/calcineurin A (PubMed:24018048). Interacts with catalytic subunit PPP3CB/calcineurin A (By similarity). Interacts with CIB1 (via C-terminal region); the interaction increases upon cardiomyocyte hypertrophy. Interacts with RCAN1 (By similarity). Interacts with SPATA33 (via PQIIIT motif) (By similarity).SUBCELLULAR LOCATION Translocates from the cytosol to the sarcolemma in a CIB1-dependent manner during cardiomyocyte hypertrophy.ALTERNATIVE PRODUCTS Isoform 2 is testis specific.MISCELLANEOUS This protein has four functional calcium-binding sites.SIMILARITY Belongs to the calcineurin regulatory subunit family. |
