Protein KIAA1958 is a protein that in humans is encoded by the KIAA1958 gene.[1] Orthologs of KIAA1958 go as far back in evolution to chordates, although, it is closer in homology to primates than any other orthologs. KIAA1958 has no known paralogs.
Gene
[edit]KIAA1958 is located on the long arm of chromosome 9 (9.q32) in humans on the plus strand from 115249248 to 115427597[2] . Its mRNA has 2683 bp[1] . The gene has these neighbors on chromosome 9:
- HSDL2: Hydroxysteroid dehydrogenase-like protein 2 plays a role in nucleotide binding, oxidoreductase activity, and sterol binding[3].
- C9orf147: Chromosome 9 open reading frame 147 has an unknown function[4] .
- C9orf80: Chromosome 9 open reading frame 80 is a component of the SOSS complex, a multiprotein complex that functions downstream of the MRN complex to promote DNA repair and G2/M checkpoint. The SOSS complex associates with single-stranded DNA at DNA lesions and influences diverse endpoints in the cellular DNA damage response including cell cycle checkpoint activation, recombinational repair and maintenance of genomic stability[5] .
- SNX30: Sorting nexin-30 may be linked to phosphatidylinositol binding[6] .

Protein
[edit]KIAA1958 is comprised of 716 amino acids and weighs 79212 Da with an iso-electric point of 6.375[7] . Although not much is known about the KIAA1958 protein, scientific predictions have been made using supercomputers for predictions of KIAA1958's structure and function. KIAA1958 undergoes post-translational modifications. The most interesting modification is phosphorylation. In comparison to other proteins, KIAA1958 has a substantially significant amount of serines phosphorylated during post-translational modification. 36 serines are predicted to be phosphorylated.
Structure
[edit]PELE on SDSC Biology WorkBench is is supercomputer that is able to predict secondary structure of the KIAA1958 protein[8]. According to this tool, the protein's secondary structure is a combination of alpha helices and beta sheets, in almost equal amount and spread out almost evenly throughout the protein.
Expression
[edit]KIAA1958 is expressed in the highest quantities in the larynx as proposed by EST[9] . The highest expression in developmental stage is the blastocyst and for health state, it is most found in uterine tumors[9] . Data from NCBI GEO Profile [10] shows that KIAA1958 expression includes many of the tissue types in the human body. Using EMBL-EBI, KIAA1958 was found to be overexpressed in pseudopod RNA during the migration of the metastatic cancer cells[11] . KIAA1958 was also overexpressed in Stat5/ab and stat 3 which are transcription factors reported to be critical for the growth and viability of prostate cancer cells[11] and both the embryonic stem cell and the pluripotent stem cell[11] .
Interactions
[edit]There is no known proof that KIAA1958 interacts with any other proteins at this time[12] .
