Golgi apparatus membrane protein TVP23 homolog B is a protein encoded by the gene TVP23B.

This gene has two paralog in the human genome, TVP23C, which is located on chromosome 17 at 17p12, and TVP23A, which is located on chromosome 16. The duplication appears to have appeared after the MRCA of humans and apes. This gene has homologs in eukaryotes as far back as Trichoplax.

Gene

TVP23B is highly conserved in chordates and also shows conservation in eukaryotes, including fungi and plants. The most common mRNA has 7 exons.

Protein

This gene encode a protein of 205 amino acids in length and a predicted molecular weight of 23.57 kDa. This protein is predicted to have an isoelectric point of 8.62. It contains a domain of unknown function, DUF846, and a predicted phosphoserine site. It is a multipass transmembrane protein and a member of the FAM18/TVP23 superfamily.

TVP23B appears to be ubiquitously expressed in all tissues, health states, and developmental stages to some level. There is also notable expression in bladder tissue.
