The RanGTPase activating protein RanGAP1 has essential functions in both nucleocytoplasmic transport and mitosis. In interphase, a significant fraction of vertebrate SUMO1-modified RanGAP1 forms a stable complex with the nucleoporin RanBP2/Nup358 at nuclear pore complexes. RanBP2 not only acts in the RanGTPase cycle but also is a SUMO1 E3 ligase. Here, we(More)
We report here the identification of a new shared human melanoma antigen recognized by a human leukocyte antigen (HLA)-A*68011-restricted cytotoxic T lymphocyte clone (CTL 128). The cDNA encoding this antigen is composed of a partially spliced form of the melanocyte differentiation antigen tyrosinase-related protein (TRP)-2, containing exons 1-4 with(More)
To assess whether RAS oncogenes may affect the expression of cytokines in tumor cells, the presence of interleukins (IL) 1 alpha, 1 beta, 4, 6, 7, and 8, tumor necrosis factor (TNF) alpha and interferon gamma mRNA has been analyzed by reverse transcriptase-polymerase chain reaction in 19 melanoma clones derived from the metastatic cell line 665/2 and(More)
