C13orf16
Chromosome 13 open reading frame 16 is a protein in homo sapiens encoded by the C13orf16 gene. There is one alias name, TEX29, for the high testis expression of this gene due to spermatogenesis.[1][2]
C13orf16 in Homo sapiens is located on the long arm of chromosome 13 at q34.[2] The spliced gene is 859 nucleotides, has 7 exons and is located on the plus strand.[1]
C13orf16 is ubiquitously expressed among human tissues, with significantly higher expression in brain tissues, specifically in the hippocampus and cerebellum.[1][3]
Protein
[edit]The human C13orf16 protein encoded by the mRNA sequence is 174 amino acids in length.[4] The molecular weight without post-transitional modifications is 18.4 KD[5] and the basal isoelectric point value is 4.99 pH.[6]
Human C13orf16 is localized both intracellularly, in the nucleus, and extracellularly with one transmembrane domain from amino acids 80-102.[4] There are no asparagines, resulting in no N-glycosylation sites.[5]
There are five interacting proteins for human C13orf16, all identified by physical interactions.[2][7][8]
| Abbreviated Name | Full Name | Brief Description |
|---|---|---|
| PTS | 6-Pyruvoyltetrahydropterin Synthase | Elimination of inorganic triphosphate from dihydroneopterin triphosphate
(2nd and irreversible step in the biosynthesis of tetrahydrobiopterin from GTP) |
| SLC16A2 | Solute Carrier Family 16 Member 2 | Non-redundant, thyroid hormone transporter |
| STEAP3 | STEAP Family Member 3, Metalloreductase | Iron transporter, can reduce both iron (Fe3+) and copper (Cu2+) cations |
| SLC4A7 | Solute Carrier Family 4 Member 7 | Sodium bicarbonate cotransporter, transports sodium and bicarbonate ions in a 1:1 ratio, considered an electroneutral cotransporter |
| SLC6A15 | Solute Carrier Family 6 Member 15 | Neutral amino acid transporter, predicted to play a role in neuronal amino acid transport |
Homology and evolution
[edit]The C13orf16 protein was only found to have orthologs in placental mammals and most distantly found in the Proboscidea taxonomic group.[9] In the table below, orthologs are sorted first by estimated date of divergence, then by sequence identity to the human C13orf16 protein.[10]
