Genes affected
SDCBP2 (HGNC:15756): (syndecan binding protein 2) The protein encoded by this gene contains two class II PDZ domains. PDZ domains facilitate protein-protein interactions by binding to the cytoplasmic C-terminus of transmembrane proteins, and PDZ-containing proteins mediate cell signaling and the organization of protein complexes. The encoded protein binds to phosphatidylinositol 4, 5-bisphosphate (PIP2) and plays a role in nuclear PIP2 organization and cell division. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. Read-through transcription also exists between this gene and the upstream FKBP1A (FK506 binding protein 1A, 12kDa) gene, as represented in GeneID:100528031. [provided by RefSeq, Sep 2011]
FKBP1A-SDCBP2 (HGNC:41997): (FKBP1A-SDCBP2 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring FK506 binding protein 1A, 12kDa and syndecan binding protein (syntenin) 2 genes on chromosome 20. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is unlikely to produce a protein product. [provided by RefSeq, Dec 2010]
