Entrez Gene Summary for CHP1 Gene

  • This gene encodes a phosphoprotein that binds to the Na+/H+ exchanger NHE1. This protein serves as an essential cofactor which supports the physiological activity of NHE family members and may play a role in the mitogenic regulation of NHE1. The protein shares similarity with calcineurin B and calmodulin and it is also known to be an endogenous inhibitor of calcineurin activity. [provided by RefSeq, Jul 2008]

GeneCards Summary for CHP1 Gene

CHP1 (Calcineurin Like EF-Hand Protein 1) is a Protein Coding gene. Among its related pathways are Glycosaminoglycan metabolism and Metabolism. Gene Ontology (GO) annotations related to this gene include calcium ion binding and microtubule binding. An important paralog of this gene is CHP2.

UniProtKB/Swiss-Prot for CHP1 Gene

  • Calcium-binding protein involved in different processes such as regulation of vesicular trafficking, plasma membrane Na(+)/H(+) exchanger and gene transcription. Involved in the constitutive exocytic membrane traffic. Mediates the association between microtubules and membrane-bound organelles of the endoplasmic reticulum and Golgi apparatus and is also required for the targeting and fusion of transcytotic vesicles (TCV) with the plasma membrane. Functions as an integral cofactor in cell pH regulation by controlling plasma membrane-type Na(+)/H(+) exchange activity. Affects the pH sensitivity of SLC9A1/NHE1 by increasing its sensitivity at acidic pH. Required for the stabilization and localization of SLC9A1/NHE1 at the plasma membrane. Inhibits serum- and GTPase-stimulated Na(+)/H(+) exchange. Plays a role as an inhibitor of ribosomal RNA transcription by repressing the nucleolar UBF1 transcriptional activity. May sequester UBF1 in the nucleoplasm and limit its translocation to the nucleolus. Associates to the ribosomal gene promoter. Acts as a negative regulator of the calcineurin/NFAT signaling pathway. Inhibits NFAT nuclear translocation and transcriptional activity by suppressing the calcium-dependent calcineurin phosphatase activity. Also negatively regulates the kinase activity of the apoptosis-induced kinase STK17B. Inhibits both STK17B auto- and substrate-phosphorylations in a calcium-dependent manner.

    Quaternary structure:
    • Monomer. Interacts with STK17B; the interaction occurs in a calcium-independent manner and induces the translocation of CHP1 from the Golgi to the nucleus. Interacts with GAPDH; the interaction is direct, occurs in a N-myristoylation-dependent manner and facilitates the ability of CHP1 to bind microtubules. Interacts with KIF1B (via the C-terminal end of the kinesin-motor domain); the interaction occurs in a calcium-dependent manner. Associates (via C-terminal domain) with microtubules; the association occurs with polymerized microtubules during the cell cycle in a myristoylation- and calcium-independent manner and is enhanced by GAPDH (By similarity). Interacts with PPP3CA. Interacts with SLC9A1/NHE1 (via the juxtamembrane region of the cytoplasmic C-terminal domain); the interaction occurs at the plasma membrane in a calcium-dependent manner and at a domain that is critical for growth factor stimulation of the exchanger.

Post-translational modifications for CHP1 Gene

  • Both N-myristoylation and calcium-mediated conformational changes are essential for its function in exocytic traffic (By similarity). N-myristoylation is required for its association with microtubules and interaction with GAPDH, but not for the constitutive association to membranes.
  • Phosphorylated; decreased phosphorylation is associated with an increase in SLC9A1/NHE1 Na(+)/H(+) exchange activity. Phosphorylation occurs in serum-dependent manner. The phosphorylation state may regulate the binding to SLC9A1/NHE1.
  • Ubiquitination at Lys40 and posLast=182182
