ICC/IF 1/1000.

This product gave a positive signal in SW480 cells fixed with 100% methanol (5 min).


  • Function

    May be involved in mediating calcium-activated chloride conductance. May play critical roles in goblet cell metaplasia, mucus hypersecretion, cystic fibrosis and AHR. May be involved in the regulation of mucus production and/or secretion by goblet cells. Involved in the regulation of tissue inflammation in the innate immune response. May play a role as a tumor suppressor. Induces MUC5AC.
  • Tissue specificity

    Highly expressed in small intestine and colon namely in intestinal basal crypt epithelia and goblet cells, and appendix. Weakly expressed in uterus, testis and kidney. Expressed in the airways epithelium of both asthmatic andhealthy patients. Expressed in the bronchial epithelium, especially in mucus-producing goblet cells. Expressed in normal turbinate mucosa and nasal polyp. Expressed in.
  • Sequence similarities

    Belongs to the CLCR family.
    Contains 1 VWFA domain.
  • Post-translational

    The 125-kDa product is processed and yields to two cell-surface-associated subunits, a 90-kDa protein and a group of 37-to 41-kDa proteins.
  • Cellular localization

    Secreted > extracellular space. Cell membrane. Protein that remains attached to the plasma membrane appeared to be predominantly localized to microvilli.

  • ab203735 staining CLCA1 in SW480 cells. The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab203735 at 1/1000 dilution (shown in red) and ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
