Chromosome 17 open reading frame 58 or C17orf58 is a protein coding human gene that located in collagen-containing extracellular matrix and encodes protein C17orf58 isoform c precursor.[5]
Gene
C17orf58 is a protein which in humans is the longest isoform encoded by the C17orf58 gene. C17orf58, also known as chromosome 17 open reading frame 58, is located on the negative strand of chromosome 17 (17q24.2) from 67,991,099 to 67,996,469, spanning 5,371 base pairs.[6]
Expression
- Gene
Gene expressed variably and ubiquitously at a moderate and high level across many tissues in humans.[7] The gene has high tissue specificity with enhanced expression in the placenta. The gene has low cell type specificity and immune cell specificity, but enriched in fibroblasts and cardiomyocytes. Expression clusters are associated with ECM organization in tissues and fibroblasts, and with innate immunity in immune cells.[8]
Clinical significance
C17orf58 is a prognostic marker in Kidney renal papillary cell carcinoma.[9] Recent research has observed overexpression of C17orf58 in T-cell lymphomas and leukemias. Since the RNA expression is relatively low in most normal cell, and C17ORF58 knockdown in T-cell lines results in the upregulation of numerous pro-apoptotic genes, it suggests that increased expression of c17orf58 might linked with the proliferation of malignant T cells.[10]
mRNA
C17orf58 contains four exons. There are 3 different transcript variants in humans through alternative splicing: transcript variant 1, transcript variant 2, transcript variant 3(see Table 1).
| Transcript variant | Accession number | Length(nt) | Exons | Protein isoform | Protein Accession number | Length(aa) |
|---|---|---|---|---|---|---|
| variant 1 | NM_181655.4 | 1,380 nt | 1,2,3 | isoform a | NP_858041.2 | 97 |
| variant 2 | NM_181656.5 | 1,523 nt | 1,2,3 | isoform b | NP_858042.2 | 75 |
| variant 3 | NM_001382359.1 | 2,105 nt | 1,2,3,4 | isoform c | NP_001369288.1 | 339 |
Protein
UPF0450 protein C17orf58 isoform c precursor is the longest isoform of c17orf58 protein. It consists of 339 amino acids. It has a molecular mass of 37~kDa and its PI is approximately 10. The protein is expressed in the nucleus in most tissues and localized to the plasma membrane and in the cytosol.[8]
Composition
C17orf58 protein is highly enriched of Arginine (R), Alanine (A) and Proline (P) and has lower amount of Threonine (T), Hydrophobic cluster (FIKMNY) and Aliphatic hydrophobic (LVIFM).[11]
Domain
The protein has three domains: Netrin-like domain, PRK07764 (DNA polymerase III subunits gamma and tau) and TIMP-like_OB-fold.[12][13]

Evolution
C17orf58 orthologs are found in mammals, birds/reptiles, amphibians and fish but not in any invertebrates( See Table 3). C17orf58 first appeared approximately 429 millions years ago in fish. C17orf58 does not belong to a multi-gene family. While the gene in humans has evolved alternative splicing to produce multiple isoforms, there are no known alternate splice isoforms of the c17orf58 protein found within the most distantly related Engraulis encrasicolus.
