C7orf25
Human protein-coding gene
From Wikipedia, the free encyclopedia
C7orf25 protein UPF0415 (UPF0415) 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 UPF0415. This protein is believed to be active in the proteosome pathway. C7orf25 protein UPF0415 is not a transmembrane protein and has no signal peptide. UPF0415 has two isoforms, Q9BPX7-1 and Q9BPX7-2. Both consists of two exons that are both highly conserved among vertebrates.

Predicted mRNA features
Promoter
The promoter for the C7orf25 protein UPF0415 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.[7] 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.
