CXorf49
CXorf49 is a protein, which in humans is encoded by the gene chromosome X open reading frame 49(CXorf49).
Gene
[edit]The CXorf49 gene has one alias CXorf49B.[1] The recname A8MYA2 also refers to the protein coded by CXorf49 or CXorf49B.[2]
CXorf49 is located on the X chromosome at Xq13.1. It is 3912 base pairs long and the gene sequence has 6 exons.[3] CXorf49 has one protein coding transcript.[4]
Protein
[edit]The protein has 514 amino acids and a molecular mass of 54.4 kDa.[5] The isoelectric point is 9.3. Compared to other human proteins CXorf49 is glycine- and proline-rich, but the protein has lower levels of asparagine, isoleucine, tyrosine and threonine(Statistical Analysis of Protein Sequences, SAPS [6]).
Domains
[edit]The domain of unknown function, DUF4641, is almost the entire protein. It is 433 amino acids long, from amino acid 80 until amino acid number 512.[7] DUF4641 is a part of pfam15483.[8] The domain is proline- and arginine-rich, but DUF4641 has lower levels of isoleucine, tyrosine and threonine compared to other proteins in human (Analysis of Protein Sequences, SAPS [6]). DUF4641 has an unusual spacing between lysine residues and positive charged amino acids (Analysis of Protein Sequences, SAPS [6]).
Post-translation modifications
[edit]CXorf49 is predicted to have several post-translational sites. This include sites for N-acetyltransferase (NetAcet 1-[9]), glycation of ε amino groups of lysines (NetGlycate 1.0[10]), mucin type GalNAc O-glycosylation (NetOglyc 4.0[11]), phosphorylation (NetPhos 2.0[12]), sumoylation (SUMOplot Analysis Program[13]) and O-ß-GlcNAc attachment(YinOYang WWW[14]).
Subcellular localization
[edit]The CXorf49 protein has been predicted to be located in the cell nucleus (PSORT II [15]).
Expression
[edit]Promoter region
[edit]The promoter region of CXorf49 is located between base pair 71718051 and 71718785 on the minus strand of the X chromosome and it is 735 bp long (Genomatix’s ElDorado program[16]). One of the most frequent transcription factor binding-sites in the promoter region are sites for Y-box binding factor.
Expression
[edit]Though expression of CXorf49 is very low in human cells, is it somewhat higher in connective tissues, testis and uterus(NCBI-Unigene [17]).
Interactions
[edit]The protein CXorf49 has not yet been shown to interact with other proteins (PSICQUIC[18]).
CXorf49 is found to be one of the components of a small group of the HL-60 cell proteome that were most prone to form 4-Hydroxy-2-nonenal(HNE) adducts, upon exposure to nontoxic (10 μM) HNE concentrations, along with heat shock 60 kDa protein 1.[19]
Homology
[edit]Using BLAST[20] no orthologs for CXorf49 are found in single celled organisms, fungi or plants whose genomes have been sequenced. For multicellular organisms orthologs are found in mammals. The table below show a selection of the mammal orthologs. They are listed after time of divergence from human.
