A novel human membrane protein, TIRC7, was recently identified and demonstrated to be essential in T cell activation. Here we report on the genomic organization of the TIRC7 gene, which is composed of 15 exons and spans 7.9 kb. The seven predicted transmembrane-spanning domains of the TIRC7 protein coincide well with exon–intron boundaries. TIRC7 and OC116, a recently described putative subunit of...
To identify novel genes induced in the early stage of T-cell activation, mRNA expression in alloactivated human lymphocytes was examined. Differential display-reverse transcription PCR analysis revealed a 207-bp cDNA fragment which was upregulated 24 h after allostimulation of a human T-cell line. The corresponding complete 1396 bp cDNA, named TGAM77, encodes a predicted 134 amino acid protein which...
DNA single-strand conformational polymorphism (SSCP) analysis is widely used for detection of point mutations in clinical specimens. Performing SSCP analysis with cRNA instead of DNA has been shown to improve mutation detection frequency. RNA can exist in numerous meta-stable conformations, which appear as patterns of bands on nondenaturing electrophoresis gels. Single base mutations can cause not...
