C11orf42

Last updated

C11orf42 is an uncharacterized protein in Homo sapiens that is encoded by the C11orf42 gene. [1] It is also known as chromosome 11 open reading frame 42 and uncharacterized protein C11orf42, with no other aliases. [2] The gene is mostly conserved in mammals, but it has also been found in rodents, reptiles, fish and worms.

Gene

Location

The gene is located on 11p15.4 and has three exons. [1] C11orf42 starts at 6205568 bp and ends at 6211319 bp. [3] C11orf42 spans 5752 base pairs and encodes in the negative strand of chromosome 11. [3]

Neighborhood

On chromosome 11, the genes FAM160A2 (gene) and OR52W1 are neighbors to C11orf42. FAM160A2 encodes in the positive strand of chromosome 11. OR52W1 encodes in the negative strand of chromosome 11.

Expression

C11orf42 is expressed in a total of seventy-four organs. [4] In a study of ninety-five individuals, twenty-seven different tissues had RNA sequencing completed to determine the tissue-specificity of the protein-coding genes. C11orf42 is expressed in a variety of tissues, although it is most broadly expressed in the skin as well as the testes. [1] According to the EST Profile of C11orf42, the protein is abundant in the bladder, brain, and testis. It was associated with bladder carcinoma and seen in the adult developmental stage. [5]

The light green represents ruptured aneurysm, the medium green represents the unruptured anuerysm, and the dark green represents the superficial temporal artery.

C11orf42 was observed in a RNA microarray that looked at different levels of intercranial aneurysms in order to see the biological heterogeneity of aneurysms. This was completed by splitting samples into groups with similar gene expressions. It was found that Kruppel-like family of transcription factors (KLF2, KLF12, and KLF15), which were anti-inflammatory regulators, were down-regulated. [6] This family of transcription factors is found in C11orf42 and it appears to have an effect on the development of aneurysm walls as a mechanical strengthener. [6] It was found that in ruptured aneurysms, C11orf42 was ranked at 55.5% among other genes and had an expression level of 8.16. In unruptured aneurysms, C11orf42 had a ranking of 50.4% and an expression level of 9.09. For the superficial temporal artery, the ranking was 35% and the expression level was 7.75. This further supports that C11orf42 has an effect in aneurysms and is involved through transcription in strengthening their walls.

Promoter

According to the Genomatix program El Dorado, the 5' UTR region is predicted to be 48 base pairs in length while the 3' UTR is 93 base pairs long. [7] Multiple sequence alignments were formed for reach UTR and there were positions found to be conserved over many orthologs. In the 5' UTR, a predicted stem loop region is found at nucleotide positions 9-25 and in the 3' UTR, the predicted stem loop region is found at nucleotide positions 1070-1084 and 1096-1112.

Red positions show important sites of post translational modifications like glycation, amidation, N-myristoylation, nuclear export signal and O-glycosylation. The blue rectangles represent the domain of unknown function and the black region represents the proline rich region of the protein.

After searching through [NCBI], it was found that C11orf42 only had a domain of unknown function called DUF4463, which is conserved from humans to worms. [12] The DUF4463 ranges from amino acid positions 4-209 and then positions 313-333. PRR stands for proline-rich region and it is located in amino acid positions 210-312. [13]

Post Translational Modifications

C11orf42 post-translational modifications C11orf42 Conceptual Translation.png
C11orf42 post-translational modifications

C11orf42 is predicted to undergo various types of post translational modifications including Glycation, O-GlcNAc, O-Glycosylation, and Phosphorylation. There was a Leucine Nuclear Export signal found at amino acid position 125. [14]

Cellular Sub Localization

C11orf42 was found to be cytoplasmic in its early life within organisms that were not mammals (Schlegel's Japanese Gecko, Acorn Worm) and then it was found to be nuclear localized as it continued to evolve in Mammalia. [15] No signal peptides, mitochondrial targeting sequences or chloroplast peptides were predicted for the protein and therefore not predicted to localize to a secretory pathway, mitochondria, nor chloroplast. [14]

Interacting Proteins

IGLL1, SNX2, and SNX5 were all found to have interacted with C11orf42. IGLL1 had a "textmining" [16] interaction with this gene while SNX2 and SNX5 had physical interactions with this gene. [17]

Clinical Significance

As seen above in the microarray expression and the tissue expression, the protein of C11orf42 may have a role in the prevalence of bladder carcinomas as well as brain aneurysms. There was another study that looked at the effect of treatment for rheumatoid arthritis that showed an influence level from C11orf42 as well, indicating that it could affect the medication available for treatment therapies like it did for anti-TNF therapy. [18] More research still needs to be done to confirm if C11orf42 has an effect in other diseases or in the treatment process of diseases.
