possess two post-translational modifications, both are phosphorylation sites with locations at amino acid 210 and 224. A natural variant is found at amino acid 110 (Glutamic acid (E)--> Lysine K). It appears as though C3orf62 may have a YinOYang site at residue 115, meaning that this Threonine residue is predicted to be O-GlycNAcylated as well as phosphorylated. This site may be reversibly and dynamically modified by O-GlcNAc or Phosphate groups at different times in the cell. Regulation of expression Thirteen promoters have been predicted for C3orf62. Transcript variants Transcription of C3orf62 produces 5 alternatively spliced variants and 1 unspliced form. Of the four splice variants, two of them are protein coding, one is nonsense meditated decay, and one is a retained intron. QIAGEN denotes the following as transcription factor binding sites in the C3orf62 promoter: TFCP2, Pax-6, p53, MyoD, YY1, Ik-2, AREB6, IRF-7A3. Function Function of C3orf62 is not currently understood by the scientific community. Interactions Upwards of 12 interacting proteins have been predicted for C3orf62. Interacting proteins with the strongest confidence to interact with C3orf62 include: HAUS augmin-like complex subunit 1 (HAUS-1), Inhibitor of growth protein 5 (ING5), Thioredoxin domain-containing protein 9 (TXNDC9), and MORF4-family associated proteins (MORF4L1, MFRAP1). Chemicals known to interact with C3orf62 include the following: Aflatoxin B1, Hydralazine, Valproic acid, and Decitabine. Clinical significance Interstitial deletions of chromosome 3 are rare, and only a few patients with a microdeletion of 3p21.31 have been reported to date. Characteristic clinical features found in patients with a microdeletion of 3p21.31 include developmental delay and distinctive facial features (including arched eyebrows, hypertelorism, epicanthus, and micrognathia). In the gene region, NCBI SNP identified 1,326 SNPS on the reverse minus strand of C3orf62. In the coding region, NCBI SNP identified 147 common SNPs. Homology Paralogs There are no known paralogs of C3orf62. Orthologs The ortholog space of C3orf62 is fairly narrow, with the majority of orthologs found in mammals. A small fraction of orthologs have also been found in the following classes: Reptila, Sarcopterygii, and Actinoptergii. The groupings of nearly all Mammalia ortholog sequences of C3orf62 are as follows: E-value: 2e-94 to 1e-169; similarity 56-84%. Mammals in this group consist largely of primates but also include the following orders: Perissodactyla, Rodentia, Carnivora, Proboscidea, Cetartiodactyla, Cingulata, Artiodactyla, Eulipotyphla, Diselphimorphia, and Afrosoricida. More distantly related ortholog sequences of C3orf62 include organisms from classes Reptilia, Sarcopterygii, and Actinopterygii ranging from an E-value of 8e-10 to
