C12orf24 (Chromosome 12, open reading frame 24) is a gene in humans (Homo sapiens) that encodes a protein known as FAM216A.[5] This gene is primarily expressed in the testis and brain, but has constitutive expression in 25 other tissues.[5][6] FAM216A is an intracellular protein that has been predicted to reside within the nucleus of cells.[7] The exact function of C12orf24 is unknown. FAM216A is highly expressed in Sertoli cells of the testis as well as different stage spermatids.[8]
Gene
[edit]Locus
[edit]C12orf24 is a protein-encoding gene found on the forward strand of chromosome 12 at the locus 12q24.11. C12orf24 is located on the long arm of chromosome 12.[9]

Expression
[edit]C12orf24 is primarily expressed in the brain, spinal cord, and testis of humans.[6][11] Within the testis C12orf24 is expressed in Sertoli cells.[8] Within the brain C12orf24 is expressed within neuropils.[12]
Gene regulation
[edit]Promoter
[edit]According to the UCSC Genome Browser and Genomatix Eldorado there are two promoters of C12orf24 and no enhancers or other regulatory elements.[13][14] Only one of the two predicted promoters binds transcription factors.[14]
Transcription factors
[edit]There are many transcription factors predicted to bind to the promoter region of C12orf24 by Genomatix and the UCSC Genome Browser.[14][13]

Protein
[edit]Cellular location
[edit]According to the PSORT program of Genescript, C12orf24 is 69.6% likely to be a nuclear protein.[7] NCBI Gene predicts that C12orf24 is an intracellular protein.[5]
Structure
[edit]Protein FAM261A has 2 charge runs, a positive run from amino acids 200-229 and a negative charge run from amino acids 238–268.[15] Methionine, histidine, and serine are all seen at a higher than expected rate in FAM216A while valine is seen at a significantly lower than expected rate.[15]
The CFSSP (Chou and Fassman Secondary Structure Prediction Server) predicts a secondary structure for FAM216A that has multiple alpha helices with a few large beta pleated sheets.[16][17] I-TASSER structure prediction program shows a 3D structure of FAM216A that has many alpha helices and a few coil turns with no beta pleated sheets.[18]

Protein level regulation
[edit]There are 8 predicted sites of sumoylation on FAM216A, with only 2 of them having a high probability of occurrence.[19] There are 7 predicted sites of glycation on FAM216A.[20] There is no predicted signal peptide for FAM216A, which may prevent the protein from being glycosylated.[21] There is 42 predicted sites for phosphorylation, however given the predicted structure of the protein not all 42 sites will be accessible for phosphorylation.[22]
Interacting proteins
[edit]There are only a few known proteins that are predicted to interact with FAM216A.[23][24][25]
Protein | Function |
---|---|
E6 | HPV type 8 protein that prevents apoptosis in infected cells |
MAGEA10 | Possible roles in embryonal development, tumor transformation, and tumor development |
DKC1 | Required for ribosome biogenesis and telomere maintenance |
RCF4 | Replication factor C subunit 4. Possible required for elongation of multiprimed DNA |
CCDC34 | Coiled-coil domain containing 34. Involved in the cell cycle |
NIFK | Nucleolar protein interacting with the FHA domain of MKI67 |
PSMA4 | Protease responsible for degrading most intracellular proteins |
Homology
[edit]Paralogs
[edit]The only paralog for FAM216A is FAM216B.[26]
Orthologs
[edit]According to the NCBI Gene page for C12orf24, there are at least 182 organisms with an ortholog of C12orf24.[27] The farthest back known orthologs are in sea corals which diverged from humans 824 million years ago.[28][29]
