C17orf64 is a protein, which in humans is encoded by the C17orf64 gene. Evidence from protein interaction experiments show that this protein interacts with other proteins that are responsible for processes, such as DNA replication, transcription, and regulation of expression. Subcellular localization experiments show that expression of the protein has been found in the nucleus and vesicles, suggesting that the function involves endocytosis. These observations together do not agree with each other, but more research into this protein could lead to more clarification about the function.

Gene
This gene is located on the plus strand at 17q23.2 and spans from 58,499,953 to 58,508,627 bp. USP32 or Ubiquitin Specific Peptidase 32 flanks C17orf64 on the minus strand.

mRNA Transcripts
The C17orf64 gene produces five other isoforms. These isoforms differ due to the start of transcription, where the promoter sequence is located. This table illustrates the differences among the various forms of the gene.

Protein Structure
C17orf64 contains:
 * One DUF4208 region
 * Number of Residues-236 amino acids
 * Molecular weight-27.1 kilodaltons
 * Isoelectric point-9.4

The secondary structure of C17orf64 is predicted to consist of alternating pairs of alpha helices and random coils.

Expression
Based on human tissue EST profiles, C17orf64 appears to be normally expressed at high levels in the testes. Low levels of expression are found in areas, such as the brain, liver, and lungs. C17orf64 expression levels appears to be higher in CD4+ cells in individuals with Multiple Sclerosis compared to the control group. This suggests that C17orf64 expression is related to the immune system.

Function
The function of C17orf64 has not yet been established in scientific literature. The evidence from immunohistochemistry experiments verify that this protein is found in the nucleus and vesicles, suggesting that this protein is involved in endocytosis.
