C2orf72 (Chromosome 2, Open Reading Frame 72) is a gene in humans ( Homo sapiens) that encodes a protein currently named after its gene, C2orf72. [5] It is also designated LOC257407 [5] and can be found under GenBank accession code NM_001144994.2. [6] The protein can be found under UniProt accession code A6NCS6. [7]
This gene is primarily expressed in the liver, brain, placental, and small intestine tissues. [8] C2orf72 is an intracellular protein that has been predicted to reside within the nucleus, cytosol, and plasma membrane of cells. [5] The function of C2orf72 is unknown, but it is predicted to be involved in very-low-density lipoprotein particle assembly and also involved in the regulation of cholesterol esterification. [9] This prediction also matches with the fact that both estradiol [10] and testosterone [11] have been reported to upregulate expression of C2orf72. [12]
C2orf72 is a protein-coding gene found on the forward (+) strand of chromosome 2 at the locus 2q37.1, on the long arm of the chromosome. [5]
C2orf72's mRNA transcript is reported to be about 3,629 base pairs long. [6] It appears to have two polyadenylation sites near the 5′ end of the mRNA transcript, each preceded by their respective regulatory sequences, such as ATTAAA or AATAAA. [6]
There are three predicted exons reported for human C2orf72. [6]
C2orf72 is preferentially expressed in brain, liver, placenta, colon, small intestine, gallbladder, stomach, and prostate, and to a lesser extent in adrenal gland, appendix, pancreas, lung, kidney, testis, and urinary bladder. [8]
It is predicted via Archs4 [13] (July 16, 2022) that the function of this gene may be related to very-low-density lipoprotein particle assembly [14] and also involved in the regulation of cholesterol esterification. [9]
In a study of embryonic liver samples lacking hepatocyte nuclear factor 4 alpha (HNF4α), the expression of C2orf72 was downregulated. [15]
Both estradiol [10] and testosterone [11] upregulate expression of C2orf72. [12]
C2orf72 mRNA and protein products are found preferentially in the liver, kidney, and placenta. [16] The protein is localized to the cell membrane and cytoplasm in liver, brain, and placental tissues. [16]
miR-1271-5p is a microRNA that could bind to the 3′ untranslated region of the C2orf72 mRNA transcript at 5′-...GUGCCAA...-3′. [6] [17] [18]
There are at least two predicted phosphorylation sites for the human C2orf72 protein, one at threonine-286 and the other at serine-294. [7]
The predicted molecular weight of C2orf72 is 30.5 kDa, [19] and it has a predicted isoelectric point (pI) of pH 8.7. [20]
There are eight cysteine residues, for a potential of four disulfide bonds. [21] Most of the cysteine residues are positioned next to a polar amino acid (uncharged or positively or negatively charged). [21]
At physiological pH, there are 33 positively charged amino acid residues, including histidine, most of which are arginines. [21] Likewise, there are 33 negatively charged amino acid residues, most of which are glutamates. [21]
There are 14 hydroxyl-containing residues (tyrosine, threonine or serine) that could serve as typical phosphorylation sites; most of these are serines. [21]
These proteins have been reported to interact with human C2orf72: RASN (GTPase NRas), [23] RASK (GTPase KRas), [23] and CD81. [24] [25]
There are at least 203 organisms with an ortholog of C2orf72. [26] The most evolutionarily distant reported ortholog of C2orf72 is in the Australian ghost shark (Callorhincus milii);, [27] [28] [29] and it is broadly conserved from Actinopterygii (bony fish) to Mammalia.
