Golgi-associated RAB2 interactor protein 2 is a protein that in humans is encoded by the GARIN2 gene (previously FAM71D). The GARIN2 protein seems to be involved in sperm movement. GARIN2 has 7 known paralogs: GARIN1A, GARIN1B, GARIN3, GARIN4, GARIN5A, GARIN5B, and GARIN6.
In humans, FAM71D is located at 14q23.3 and stretches between positions 67189393 and 67228550 (span 39157 bp). It codes for at least 10 unique human protein isoforms: the primary isoform (422 aa; also denoted X1), isoform X2 (417 aa), isoform X3 (413 aa), isoform X4 (400 aa), isoform X5 (399 aa), isoform X6 (398 aa), isoform X7 (392 aa), isoform X8 (389 aa), isoform X9 (347 aa), isoform X10 (336 aa) 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 The gene has the following neighbours on the same chromosome:

The primary protein encoded by FAM71D in humans is 422 amino acids long with a molecular weight of 47076 Da. The protein is part of a functionally uncharacterized family of proteins (pfam 12480) with a domain of unknown function DUF3699.
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. According to this tool, the protein's secondary structure is mostly alpha helices, beta stands and coiled-coiled domains.
Like any other protein, this protein undergoes post-translational modifications. FAM71D is predicted to contain 2 nuclear export signals, and lacks both a signal peptide and transmembrane domains.
FAM71D interacts with PGK2, TUBA3C, and HSPB1. FAM71D is also predicted to interact with the following proteins using STRING:
FAM71D is primarily expressed in the testis of humans only expressed during the adult developmental stage. GEO microarray data also supports the expression of FAM71D in humans
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.
