| Gene Summary | C19orf48 as the gene encoding a novel minor H antigen presented by HLA-A*0201 and recognized by CTL clones isolated from two patients with metastatic RCC who were treated with nonmyeloablative HLA-identical allogeneic HCT. The C19orf48 gene, first identified by the Mammalian Gene Collection Program, was subsequently cloned from a cisplatin-resistant human lung adenocarcinoma cell line. Sequence analysis of C19orf48 transcripts predicted a 117-residue translation product encoded by the largest ORF that is located in both the NM_199250 and NM_199249 transcripts. The studies of T cell recognition of C19orf48 provide direct evidence for a translation product derived from a novel ORF in the +2 frame of NM_199250 that encodes a predicted polypeptide of only 48 residues. Although differential splicing of 5 exons result in the alternative C19orf48-derived transcripts NM_199249 or NM_199250 that are discordant for the ORF encoding the antigenic 48-residue protein, our analyses of transcript expression by both northern blot and Q-PCR demonstrate that the NM_199250 transcript encoding the antigenic 48 residue polypeptide is the dominant transcript, with expression levels that are 100- to 600-fold greater than the expression levels of NM_199249. Discovery of the C19orf48-encoded minor H antigen within an unrecognized ORF adds to a growing body of data demonstrating that minor H peptides can be derived from surprisingly short protein species encoded by unconventional or occult ORFs. The C19orf48 genomic locus lies between the androgen-regulated testicular acid phosphatase (ACPT) gene and the androgen-regulated kallikrein gene cluster on chromosome 19q. |
