Papers on alpha4 phosphoprotein
alpha4 phosphoprotein interacts with EDD E3 ubiquitin ligase and poly(A)-binding protein.
Too et al., Halifax, Canada. In J Cell Biochem, 2010
Mammalian alpha4 phosphoprotein, the homolog of yeast Tap42, is a component of the mammalian target-of-rapamycin (mTOR) pathway that regulates ribogenesis, the initiation of translation, and cell-cycle progression.
Overexpression of the mTOR alpha4 phosphoprotein activates protein phosphatase 2A and increases Stat1alpha binding to PIAS1.
Too et al., Halifax, Canada. In Mol Cell Endocrinol, 2007
Alpha4 phosphoprotein in the mTOR pathway is a prolactin (PRL)-downregulated gene product that interacts with the catalytic subunit of serine/threonine protein phosphatase 2A (PP2Ac) in rat Nb2 lymphoma cells.
Role of O-linked beta-N-acetylglucosamine modification in the subcellular distribution of alpha4 phosphoprotein and Sp1 in rat lymphoma cells.
Too et al., Halifax, Canada. In J Cell Biochem, 2005
The mTOR alpha4 phosphoprotein is a prolactin (PRL)-downregulated gene product that is found in the nucleus of PRL-dependent rat Nb2 lymphoma cells.
Characterization of a novel, cytokine-inducible carboxypeptidase D isoform in haematopoietic tumour cells.
Too et al., Halifax, Canada. In Biochem J, 2005
The Nb2 CPD-N co-immunoprecipitated with phosphatase PP2A (protein phosphatase 2A) and alpha4 phosphoprotein.
Implication of alpha4 phosphoprotein and the rapamycin-sensitive mammalian target-of-rapamycin pathway in prolactin receptor signalling.
Too et al., Halifax, Canada. In J Endocrinol, 2002
A prolactin (PRL)-responsive 3'-end cDNA encoding rat alpha4 phosphoprotein was previously isolated from a rat lymphoma cDNA library.
Differential expression of elongation factor-2, alpha4 phosphoprotein and Cdc5-like protein in prolactin-dependent/independent rat lymphoid cells.
Too, Halifax, Canada. In Mol Cell Endocrinol, 1997
By screening an Nb2-Sp cDNA library with 6ac1.12 as probe, three unique genes were isolated and identified as elongation factor 2 (EF-2), alpha4 phosphoprotein and a Cdc5-like protein.
Intracellular Ca2+ stores of rat cerebellum: heterogeneity within and distinction from endoplasmic reticulum.
Volpe et al., Padova, Italy. In Biochem J, 1993
The distribution of endoplasmic reticulum (ER) markers (RNA, signal-sequence receptor alpha, calnexin, calreticulin, the immunoglobulin-binding protein Bip) and markers of intracellular rapidly exchanging Ca2+ stores [Ca2+ channels sensitive to either Ins(1,4,5)P3 or ryanodine) was investigated biochemically and immunologically.
