Summaries for PANX1 Gene

Entrez Gene Summary for PANX1 Gene

  • The protein encoded by this gene belongs to the innexin family. Innexin family members are the structural components of gap junctions. This protein and pannexin 2 are abundantly expressed in central nerve system (CNS) and are coexpressed in various neuronal populations. Studies in Xenopus oocytes suggest that this protein alone and in combination with pannexin 2 may form cell type-specific gap junctions with distinct properties. [provided by RefSeq, Jul 2008]

GeneCards Summary for PANX1 Gene

PANX1 (Pannexin 1) is a Protein Coding gene. Diseases associated with PANX1 include Pineal Parenchymal Tumor Of Intermediate Differentiation and Basilar Artery Occlusion. Among its related pathways are Transmission across Chemical Synapses and Immune System. GO annotations related to this gene include protein heterodimerization activity and actin binding. An important paralog of this gene is PANX3.

UniProtKB/Swiss-Prot for PANX1 Gene

  • Structural component of the gap junctions and the hemichannels. May play a role as a Ca(2+)-leak channel to regulate ER Ca(2+) homeostasis.

Tocris Summary for PANX1 Gene

  • Gap channels (gap junctions) are specialized cell-cell contacts that provide direct intracellular communication. They allow passive diffusion of molecules up to 1 kDa, including nutrients, metabolites (glucose), ions (K+, Ca2+) and second messengers (IP3, cAMP).
