Protein JTB

UniProt data

UniProt name: JTB_HUMAN (O76095)

Gene name: JTB; ORFNames=HSPC222

Organism: Homo sapiens (Human).

Function: Required for normal cytokinesis during mitosis. Plays a role in the regulation of cell proliferation. May be a component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. Increases AURKB activity. Inhibits apoptosis induced by TGFB1 (By similarity). Overexpression induces swelling of mitochondria and reduces mitochondrial membrane potential (By similarity). {ECO:0000250, ECO:0000269|PubMed:21225229}.

Subcellular location: Membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000305}. Mitochondrion {ECO:0000250}. Cytoplasm. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, spindle. Note=Detected at the centrosome and along spindle fibers during prophase and metaphase. Detected at the midbody during telophase.

Transmembrane domains:

  1. 106-126, 21 AA, Helical. {ECO:0000255}.

Sequence: 146 AA
