Chromosome 9 open reading frame 152 is a protein that in humans is encoded by the C9orf152 gene .[1] [2] The exact function of the protein is not completely understood.
Gene
The human gene C9orf152 is located on the long (q) arm of Chromosome 9 .[3] Its cytogenetic location is 9q31.1. It has one known alias: bA470J20.2.[4]
The DNA sequence encoding C9orf152 contains a single intron .[3] The final mRNA consists of 2698 base pairs . Nucleotides 66-68 encode an upstream in frame stop codon.[1]

Evolution
C9orf152 has orthologs in mammals , birds , reptiles and amphibians . No orthologs have been detected in bony fish or in any invertebrates .[3] [5] The following table lists a subset of conserved orthologs.
Differences among shown orthologs suggest a slow rate of evolution.[6]
Protein
Chromosome 9 open reading frame 152 contains 239 amino acids . The molecular weight is 26.3 kilodaltons . The protein has a high chance of existing nuclear region of cells.[7] There are likely no transmembrane regions .[8] One isoform exists, containing 194 amino acids.[5] [9]
Within the coding sequence, there are two sumoylation sites[10] [11] [12] and a single serine phosphorylation site.[13]
There are three regions predicted to form alpha helices on the final protein.[14] [15]
Expression

C9orf152 is expressed in the bladder , intestine , mammary gland , and trachea and in smaller amounts in the lungs , liver , prostate , uterus , and brain .[16] Within the brain, expression of C9orf152 is limited to the olfactory bulb .[17] Gene expression was found to increase in the presence of stress, including disease and heat stress .[18]
A wide variety of transcription factors interact with the promoter of C9orf152, most notably two olfactory related factors (specifically, a neuron-specific olfactory factor and an olfactory associated zinc finger protein) and a negative glucocorticoid response element.[19]
