Шаблон:Short description Шаблон:Infobox gene FAM71D, also known as chromosome 14 open reading frame 54 (C14orf54), is a protein that in humans is encoded by the FAM71D gene on Chromosome 14.[1] Orthologs of FAM71D reach as far back in evolution to Reptiles, however, it is closer in homology to primates than any other orthologs. FAM71D has 6 paralogs: FAM71A, FAM71B, FAM71C, FAM71E1, FAM71F1, and FAM71F2[2] which encode a protein of unknown function.

Gene

In humans, FAM71D is located at 14q23.3 and stretches between positions 67189393 and 67228550 (span 39157 bp).[3] It codes for at least 10 unique human protein isoforms: the primary isoform (422 aa; also denoted X1),[4][5][6][7] isoform X2 (417 aa),[8] isoform X3 (413 aa),[9] isoform X4 (400 aa),[10] isoform X5 (399 aa),[11] isoform X6 (398 aa),[12] isoform X7 (392 aa),[13][14] isoform X8 (389 aa),[15] isoform X9 (347 aa),[16] isoform X10 (336 aa)[17] In humans, FAM71D codes for an mRNA strand that is 1790 base pairs long. The human mRNA is composed of a 5' untranslated region that is 290 bases long and a 3' untranslated region that is 231 bases long[18] The gene has the following neighbours on the same chromosome:

Protein

The primary protein encoded by FAM71D in humans is 422 amino acids long with a molecular weight of 47076 Da.[21] The protein is part of a functionally uncharacterized family of proteins (pfam 12480) with a domain of unknown function DUF3699.[22]

Structure

Several tools are available to predict the secondary structure of a protein. One tool that combines the results of few of them is PELE on SDSC Biology WorkBench.[23] According to this tool, the protein's secondary structure is mostly alpha helices, beta stands and coiled-coiled domains.

Post Translational Modifications

Like any other protein, this protein undergoes post-translational modifications. FAM71D is predicted to contain 2 nuclear export signals,[24] and lacks both a signal peptide[25] and transmembrane domains.[26]

Interactions

FAM71D interacts with PGK2,[27] TUBA3C,[27] and HSPB1.[28] FAM71D is also predicted to interact with the following proteins using STRING:[29]

THUMPD3: THUMP domain containing 3
CCDC170: Coiled-coil domain containing 170
KLH10: Kelch-like 10
TMEM48: Transmembrane protein 48
SHCBP1L: SHC SH2-domain binding protein
ASNA1: arsA arsenite transporter
PPP1R16A: Protein Phosphate 1, regulatory subunit 16A
IZUMO1: izumo sperm-egg fusion 1
SF3B2: Splicing factor 3b, submit 2
TUBB4B: Tubulin, beta 4B class IVb

Expression

FAM71D is primarily expressed in the testis of humans only expressed during the adult developmental stage.[30] GEO microarray data also supports the expression of FAM71D in humans[31]

Clinical Relevance

No studies have directly associated FAM71D protein with certain diseases. However, using NCBI GEO Profiles, FAM71D was found to be over-expressed in patients with unruptured intracranial aneurysms.
