Related Product Information for anti-ST5 antibody

ST5 was identified by its ability to suppress the tumorigenicity of Hela cells in nude mice. The protein contains a C-terminal region that shares similarity with the Rab 3 family of small GTP binding proteins. This protein preferentially binds to the SH3 domain of c-Abl kinase, and acts as a regulator of MAPK1/ERK2 kinase, which may contribute to its ability to reduce the tumorigenic phenotype in cells.

NCBI Description

This gene was identified by its ability to suppress the tumorigenicity of Hela cells in nude mice. The protein encoded by this gene contains a C-terminal region that shares similarity with the Rab 3 family of small GTP binding proteins. This protein preferentially binds to the SH3 domain of c-Abl kinase, and acts as a regulator of MAPK1/ERK2 kinase, which may contribute to its ability to reduce the tumorigenic phenotype in cells. Three alternatively spliced transcript variants of this gene encoding distinct isoforms are identified. [provided by RefSeq, Jul 2008]

Uniprot Description

DENND2B: a guanine nucleotide exchange factor (GEF) that may activate RAB9A and RAB9B. May be involved in cytoskeletal organization and tumorogenicity. Widely expressed with the exception of peripheral blood lymphocytes and lymphoid cell lines. 3 isoforms of the human protein are produced by alternative promoter. Isoform 1 interacts with the SH3 domain of ABL1, is expressed in several epithelial, fibroblast, and tumorigenic cell lines, and seems to be involved in the activation of ERK2. Isoform 3, expressed in primary cells that may be weakly tumorigenic, but not in tumorigenic cell lines, may block ERK2 activation stimulated by ABL1, and may alter cell morphology and cell growth.

Protein type: GEFs; GEFs, Rab

Chromosomal Location of Human Ortholog: 11p15
