Genetic analysis of the Kirsten-ras-revertant 1 gene: potentiation of its tumor suppressor activity by specific point mutations.

Kitayama, H, Matsuzaki, T, Ikawa, Y, Noda, M

Kirsten-ras-revertant 1 (Krev-1) cDNA encodes a ras-related protein and exhibits an activity of inducing flat revertants at certain frequencies (2-5% of total transfectants) when introduced into a...

Identification of Rap1 as a target for the Crk SH3 domain-binding guanine nucleotide-releasing factor C3G.

Gotoh, T, Hattori, S, Nakamura, S, Kitayama, H, Noda, M, Takai, Y, ...

C3G, which was identified as a Crk SH3 domain-binding guanine nucleotide-releasing factor, shows sequence similarity to CDC25 and Sos family proteins (S. Tanaka, T. Morishita, Y. Hashimoto, S....

Detection of genes with a potential for suppressing the transformed phenotype associated with activated ras genes.

Noda, M, Kitayama, H, Matsuzaki, T, Sugimoto, Y, Okayama, H, Bassin, R H, ...

Seven morphologically nontransformed (flat) revertants with reduced tumorigenicity in vivo have been isolated from populations of Kirsten sarcoma virus-transformed NIH 3T3 cells transfected with a...

Identification of mutations in the coding sequence of the proto-oncogene c-kit in a human mast cell leukemia cell line causing ligand-independent activation of c-kit product.

Furitsu, T, Tsujimura, T, Tono, T, Ikeda, H, Kitayama, H, Koshimizu, U, ...

The c-kit proto-oncogene encodes a receptor tyrosine kinase. Binding of c-kit ligand, stem cell factor (SCF) to c-kit receptor (c-kitR) is known to activate c-kitR tyrosine kinase, thereby leading to...

Three distinct activities possibly involved in mRNA splicing are found in a nuclear fraction lacking U1 and U2 RNA.

Mayeda, A, Tatei, K, Kitayama, H, Takemura, K, Ohshima, Y

A nuclear extract from HeLa cells was fractionated by DEAE-Sepharose chromatography, and the fractions were assayed for the binding activity for a small RNA transcript carrying a splice junction or...

Genetic analysis of the K-rev-1 transformation-suppressor gene.

Kitayama, H, Matsuzaki, T, Sugimoto, Y, Ikawa, Y, Noda, M

Flat revertants with reduced malignancy in vivo can be isolated from Kirsten sarcoma virus-transformed NIH 3T3 cells (DT line) following transfection with a normal human fibroblast cDNA expression...
