Protein Information (annotations from UniProt)

Database IDHIV0006705
UniProt IDQ9NW64
Primary gene name(s)RBM22
Synonym gene name(s)ZC3H16
Protein namePre-mRNA-splicing factor RBM22
Protein functionInvolved in the first step of pre-mRNA splicing. Binds directly to the internal stem-loop, ISL domain of the U6 snRNA and to the pre-mRNA intron near the 5' splice site during the activation and catalytic phases of the spliceosome cycle. Involved in both translocations of the nuclear SLU7 to the cytoplasm and the cytosolic calcium-binding protein PDCD6 to the nucleus upon cellular stress responses. {ECO:0000269|PubMed:17045351, ECO:0000269|PubMed:21122810, ECO:0000269|PubMed:22246180}.
Subcellular locationNucleus. Cytoplasm. Note=Mainly located in the nucleus. Translocated from the nucleus to the cytoplasm after heat shock cell treatment. May be shuttling between the nucleus and the cytosol.
