Summary
UPK3B is a minor component of the apical plaques of mammalian urothelium that binds and dimerizes with uroplakin-1b (UPK1B; MIM 602380), one of the major conserved urothelium membrane proteins. The other major conserved integral membrane proteins of urothelial plaques are UPK1A (MIM 611557), UPK2 (MIM 611558), and UPK3A (MIM 611559) (Deng et al., 2002 [PubMed 12446744]).[supplied by OMIM, Mar 2008]

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.

mRNA and Protein(s)

  1. NM_001347684.2 → NP_001334613.1  uroplakin-3b isoform d precursor

    Status: VALIDATED

    Description
    Transcript Variant: This variant (4) is alternatively spliced at the 5' end, differs in the 3' UTR and contains an additional internal exon, which causes a frame-shift compared to variant 1. The resulting isoform (d) lacks a protein segment in the N-terminal region and has a distinct C-terminus compared to isoform a. This variant is annotated on the GRCh38 primary human reference genome assembly.
