DUB-1, a deubiquitinating enzyme with growth-suppressing activity.
Cytokines regulate cell growth by inducing the expression of specific target genes. Using the differential display method, we have cloned a cytokine-inducible immediate early gene, DUB-1 (for deubiquitinating enzyme). DUB-1 is related to members of the UBP superfamily of deubiquitinating enzymes, which includes the oncoprotein Tre-2. A glutathione S-transferase-DUB-1 fusion protein cleaved ubiq...
متن کاملDUB-2A, a new member of the DUB subfamily of hematopoietic deubiquitinating enzymes.
Protein ubiquitination is an important regulator of cytokine-activated signal transduction pathways and hematopoietic cell growth. Protein ubiquitination is controlled by the coordinate action of ubiquitin-conjugating enzymes and deubiquitinating enzymes. Recently a novel family of genes encoding growth-regulatory deubiquitinating enzymes (DUB-1 and DUB-2) has been identified. DUBs are immediat...
متن کاملSurvey of the Phosphorylation Status of the Schizosaccharomyces pombe Deubiquitinating Enzyme (DUB) Family
Ubiquitination plays a role in virtually every cellular signaling pathway ranging from cell cycle control to DNA damage response to endocytosis and gene regulation. The bulk of our knowledge of the ubiquitination system is centered on modification of specific substrate proteins and the enzymatic cascade of ubiquitination. Our understanding of the regulation of the reversal of these modification...
متن کاملThe deubiquitinating enzyme DUB-2 prolongs cytokine-induced signal transducers and activators of transcription activation and suppresses apoptosis following cytokine withdrawal.
Cytokines, such as interleukin-2 (IL-2), activate intracellular signaling pathways via rapid tyrosine phosphorylation of their receptors, resulting in the activation of many genes involved in cell growth and survival. The deubiquitinating enzyme DUB-2 is induced in response to IL-2 but as yet its function has not been determined. The results of this study show that DUB-2 is expressed in human T...
متن کاملA mutant deubiquitinating enzyme (Ubp-M) associates with mitotic chromosomes and blocks cell division.
A new ubiquitin-processing protease (Ubp-M) has been identified in mammalian cells that is phosphorylated at the onset of mitosis and dephosphorylated during the metaphase/anaphase transition. The carboxyl-terminal domain of this 823-aa protein can be phosphorylated in vitro with either extracts of mitotic cells or purified cdc-2/cyclin B complexes. Recombinant Ubp-M is able to deubiquitinate h...
