Transmembrane protein 126B is a protein that in humans is encoded by the TMEM126B gene. TMEM126B is a transmembrane protein with unknown function. The Tmem126b gene is conserved in mammals.

Discovery

TMEM126B was first discovered in a study of protein expression in tissues of the hypothalamus-pituitary-adrenal axis using full cDNA cloning. It has since been detected in other tissues.

Gene

TMEM126B is located on chromosome 11 in humans, flanked by the following genes:

  • DLG2: A member of the membrane-associated guanylate kinase family.
  • TMEM126A: A paralog of TMEM126B expressed in the mitochondria.
  • CREBZF: Also known as the Zhangfei protein, a protein that interacts with herpes simplex virus.
  • Translation

    A conceptual translation of the TMEM126B protein, including a projection of the secondary structure, predictions of transmembrane regions, and putative phosphorylation and glycation sites is included below:

    Tissue distribution

    TMEM126B is expressed in most tissue types, with the notable exceptions of adipose tissue, ear tissue, the larynx, lymph tissue, nerve tissue, pituitary gland, spleen, thymus, thyroid, trachea, and umbilical cord. It also appears to be highly expressed in parathyroid, bone marrow, and urinary bladder tissue. There is also evidence that one of the isoforms of TMEM126B is expressed in the cell membrane of memory B cells of the adaptive immune system.

    Predicted properties

    The following properties of TMEM126B were predicted using bioinformatic analysis:

  • Molecular Weight: 22.7 KDal
  • Isoelectric point: 9.02
  • TMEM126B orthologs have highly variable isoelectric points.
  • Post-translational modification: several possible phosphorylation sites were detected, and a pair of possible glycation sites were predicted
  • No signal peptide has been predicted.
  • Structure

    A cartoon representation, tentatively based on the phosphorylation and hydrophobicity data is shown below.
