Description:
The retinoblastoma (Rb) antioncogene encodes a nuclear phosphoprotein, p105-Rb, that forms protein complexes with the adenovirus E1A and SV40 large T oncoproteins. A novel, aberrant Rb protein detected in J82 bladder carcinoma cells was not able to form a complex with E1A and was less stable than p105-Rb. By means of a rapid method for the detection of mutations in Rb mRNA, this defective Rb protein was observed to result from a single point mutation within a splice acceptor sequence in J82 genomic DNA. This mutation eliminates a single exon and 35 amino acids from its encoded protein product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horowitz, J M -- Yandell, D W -- Park, S H -- Canning, S -- Whyte, P -- Buchkovich, K -- Harlow, E -- Weinberg, R A -- Dryja, T P -- CA 08131/CA/NCI NIH HHS/ -- CA 13106/CA/NCI NIH HHS/ -- CA 39826/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Feb 17;243(4893):937-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Massachusetts Institute of Technology, Cambridge 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2521957" target="_blank"〉PubMed〈/a〉
