  • WB - Connexin 43 Antibody (N-term) AP1541b
    Western blot analysis of lysates from Hela, U-87 MG, C6 cell line and mouse heart tissue lysate (from left to right), using GJA1 Antibody (N121)(Cat. #AP1541b). AP1541b was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysates at 35ug per lane.
  • WB - Connexin 43 Antibody (N-term) AP1541b
    (LEFT)Western blot analysis of anti-GJA1 Antibody (N-term)(Cat.#AP1541b) in CEM cell line lysates (35ug/lane). GJA1(arrow) was detected using the purified Pab.(RIGHT)Western blot analysis of hGJA1-N121.Connexin (Cat.#AP1541b) in mouse brain tissue lysates (35ug/lane).GJA1 (arrow) was detected using the purified Pab.
  • IHC-P - Connexin 43 Antibody (N-term) AP1541b
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

Protein Information
Name GJA1
Synonyms GJAL
Function Gap junction protein that acts as a regulator of bladder capacity. A gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell. May play a critical role in the physiology of hearing by participating in the recycling of potassium to the cochlear endolymph. Negative regulator of bladder functional capacity: acts by enhancing intercellular electrical and chemical transmission, thus sensitizing bladder muscles to cholinergic neural stimuli and causing them to contract (By similarity). May play a role in cell growth inhibition through the regulation of NOV expression and localization. Plays an essential role in gap junction communication in the ventricles (By similarity).
Cellular Location Cell membrane; Multi-pass membrane protein. Cell junction, gap junction. Endoplasmic reticulum {ECO:0000250|UniProtKB:P23242}. Note=Localizes at the intercalated disk (ICD) in cardiomyocytes and the proper localization at ICD is dependent on TMEM65. {ECO:0000250|UniProtKB:P23242}
Tissue Location Expressed in the heart and fetal cochlea.

Background

Gap junction protein, alpha 1 is a member of the connexin gene family and a component of gap junctions. Gap junctions are composed of arrays of intercellular channels and provide a route for the diffusion of materials of low molecular weight from cell to cell. Connexin 43 is the major protein of gap junctions in the heart, and gap junctions are thought to have a crucial role in the synchronized contraction of the heart and in embryonic development. Connexin 43 is targeted by several protein kinases that regulate myocardial cell-cell coupling. A related intron-less connexin 43 pseudogene, GJA1P, has been mapped to chromosome 5.
