 C7orf25 protein UPF1015  is a protein encoded on chromosome 7, in open reading frame 25 (C7orf25) and are located at domain of unknown function 1308. C7orf25 is located at the minus strand and encodes 12 proteins, one of them being UPF1015. This protein is believed to be active in the proteosome pathway. C7orf25 protein UPF1015 is not a transmembrane protein and has no signal peptide. UPF1015 has two isoforms, Q9BPX7-1 and Q9BPX7-2. Both consists of two exons that are both highly conserved among vertebrates.

Gene Neighborhood
C7orf25 is an open reading frame that encodes 12 proteins. Most of these are of unknown function. One of these proteins is UPF1015 and another is PSMA2 which is also functional in the proteosome pathway. Other genes located near C7orf25 protein UPF1015 are TCP1P1, HECW1, MIR3943 and MRPL32.

Promoter
The promoter for the C7orf25 protein UPF1015 gene spans 600 base pairs from 42,951,804 to 42,952,404 with a predicted transcriptional start site that encodes a sequence of 1844 base pairs. The sequence spans from 42,908,726 to 42,912,090. The promoter region and beginning of the C7orf25 gene (20,008,263 to 20,009,250) is not conserved past primates. This region was used to determine transcription factor interactions.

 Transcription factors 

Some of the main transcription factors that bind to the promoter are listed below.

Function and expression
C7orf25 protein UPF1015 is believed to be active in ATP dependent protein breakdown in the proteosome pathway. It is expressed ubiquitously in humans.

Homology
UPF0415 protein C7orf25 has one paralog which is FLJ18411. UPF0415 is also highly conserved in vertebrates. The following table shows a small selection of orthologs found using BLAST and BLAT and their identity to C7orf25 protein UPF1015.

Post Translational Modifications
UPF0415 protein C7orf25 is not a transmembrane protein as it has no transmembrane domains. UPF0415 protein C7orf25 has multiple phosphorylation. These sites are believed to be responsible in protein activation.

Multiple stem loops have been identified in both 3` and 5`UTR and these are believed to be functional in gene transcription.

Interactions
Other proteins that are known to interact with UPF0415 protein C7orf25 are FRA10AC1, FLJ23825 and TUBB (tubulin, beta class I) and only TUBB is associated with proteosome activity.

Conceptual presentation
All post transnational modifications, genetic or proteomic factors that are relevant for UPF0415 protein C7orf25 transcription and regulation, mentioned above, are annotated in the conceptual translation.



C7orf25
C7orf25 encodes 12 different transcripts. Two of these transcripts are (PSMA2 and UPF0415). No specific phenotypes or polymorphisms are yet to be related to mutations in C7orf25. This suggests that this reading frame is important for survival in vertebrates. The picture bellow shows all predicted transcripts encoded in C7orf25.
