The retinoblastoma interacting zinc finger gene RIZ produces a PR domain-lacking product through an internal promoter.
The PR domain is a newly recognized protein motif that characterizes a subfamily of Krüppel-like zinc finger genes. Members of the PR domain family have been shown to play important roles in cell differentiation and malignant transformation. The RIZ gene is the founding member of this family; it was isolated because its gene products can bind to the retinoblastoma tumor suppressor protein. Here...
متن کاملThe retinoblastoma protein-interacting zinc finger gene RIZ in 1p36-linked cancers.
Mutations or changes in protooncogenes and tumor suppressor genes are casually linked to human cancer pathogenesis. The RIZ gene is isolated based on the capacity its gene products to bind to the retinoblastoma tumor suppressor protein. Consistent with a potential role in the Rb pathway, RIZ may play an important role in human cancer pathogenesis. RIZ maps to human chromosome band 1p36, a regio...
متن کاملThe retinoblastoma-interacting zinc-finger protein RIZ is a downstream effector of estrogen action.
Co-immunoprecipitation experiments in cell extract from cultured cells or target tissues indicated that estrogen receptor was complexed with the retinoblastoma binding protein RIZ in a ligand-dependent manner. Mapping of interaction sites indicated that in both proteins the same regions and motifs responsible for the interaction of transcriptional co-activator and nuclear receptors were involve...
متن کاملPRDI-BF1-RIZ domain of retinoblastoma protein-interacting zinc finger gene 1 induces apoptosis and exerts anticancer activity in esophageal squamous cell carcinoma cells
The present study examined the role of the PRDI-BF1-RIZ (PR) domain of tumor suppressor retinoblastoma protein-interacting zinc finger gene 1 (RIZ1) as an anticancer domain and its ability to induce apoptosis in esophageal squamous cell carcinoma (ESCC) cells. The TE13 ESCC cell line was transfected with pcDNA3.1(+) eukaryotic expression vectors bearing the open reading frames of either the hum...
متن کاملRIZ1, but not the alternative RIZ2 product of the same gene, is underexpressed in breast cancer, and forced RIZ1 expression causes G2-M cell cycle arrest and/or apoptosis.
The retinoblastoma protein-interacting zinc finger gene RIZ maps to the distal short arm of human chromosome 1 (1p36), a region thought to harbor tumor suppressor genes for a variety of human cancers including breast cancer. The RIZ gene normally produces two protein products of different length, RIZ1 and RIZ2. RIZ2 is generated by an internal promoter and lacks an NH2-terminal motif of RIZ1, t...
