Journal ArticleDOI

Similarity of protein encoded by the human c-erb-B-2 gene to epidermal growth factor receptor.

TL;DR: Its sequence shows that the c-erb-B-2 gene encodes a possible receptor protein and allows an analysis of the similarity of the protein to the EGF receptor and the neu product.
Journal ArticleDOI

A v-erbB-related protooncogene, c-erbB-2, is distinct from the c-erbB-1/epidermal growth factor-receptor gene and is amplified in a human salivary gland adenocarcinoma

TL;DR: Southern blot analysis showed close similarity of the restriction patterns of the rat c-erbB-2 gene and the rat neu oncogene, suggesting possible involvement of c- Derbyshire-related DNA clones in human cancer.
Journal ArticleDOI

Characterization of Fyn-mediated tyrosine phosphorylation sites on GluRε2 (NR2B) subunit of the N-methyl-D-aspartate receptor

TL;DR: Tyr-1472 phosphorylation of GluRε2 was greatly reduced infyn mutant mice and significantly enhanced after induction of long term potentiation in the hippocampal CA1 region, suggesting that Tyr-1336, Tyr-1252, and Tyr- 1472 in Glu Rε2 were phosphorylated in human embryonic kidney fibroblasts when co-expressed with active Fyn, and its magnitude became larger in murine brain.
Journal ArticleDOI

Amplification and enhanced expression of the epidermal growth factor receptor gene in A431 human carcinoma cells

TL;DR: Results are consistent with the hypothesis that, in A431 cells, gene amplification, possibly associated with a translocation event, may result in the overproduction of EGF receptor protein or the appearance of the transformed phenotype (or both).
Journal ArticleDOI

Localization of a novel v-erbB-related gene, c-erbB-2, on human chromosome 17 and its amplification in a gastric cancer cell line

TL;DR: The c-erbB-2 gene is a v-erb B-related proto-oncogene which is distinct from the gene encoding the epidermal growth factor receptor, and a specific breakpoint observed in a translocation associated with acute promyelocytic leukemia is mapped.
