    Summary
    This gene encodes a membrane-bound protein that is a member of the mucin family. Mucins are O-glycosylated proteins that play an essential role in forming protective mucous barriers on epithelial surfaces. These proteins also play a role in intracellular signaling. This protein is expressed on the apical surface of epithelial cells that line the mucosal surfaces of many different tissues including lung, breast stomach and pancreas. This protein is proteolytically cleaved into alpha and beta subunits that form a heterodimeric complex. The N-terminal alpha subunit functions in cell-adhesion and the C-terminal beta subunit is involved in cell signaling. Overexpression, aberrant intracellular localization, and changes in glycosylation of this protein have been associated with carcinomas. This gene is known to contain a highly polymorphic variable number tandem repeats (VNTR) domain. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Feb 2011]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      See identical proteins and their annotated locations for NP_001191225.1

      Status: REVIEWED

      Description
      Transcript Variant: This variant (20) has multiple differences compared to variant 1, one of which results in a translational frameshift in the central coding region. The encoded isoform (20) is shorter than isoform 1.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (21) has multiple differences but maintains the reading frame, compared to variant 1. These differences result in a shorter isoform (21), compared to isoform 1.

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NG_029383.1: Suppressed sequence

      Description
      NG_029383.1: This RefSeq was removed because currently there is insufficient data to represent an accurate genomic sequence.
    2. NM_001018021.1: Suppressed sequence

      Description
      NM_001018021.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.
    3. NM_182741.1: Suppressed sequence

      Description
      NM_182741.1: This RefSeq was permanently suppressed because currently there is insufficient support from non-cancerous tissues for the transcript and protein.
