Stat1 and SUMO modification.
Many proteins are known to undergo small ubiquitin-related modifier (SUMO) modification by an E1-, E2-, and E3-dependent ligation process. Recognition that protein inhibitor of activated signal transducers and activators of transcription (STATs) (PIAS) proteins are SUMO E3 ligases raised the possibility that STATs may also be regulated by SUMO modification. Consistent with this possibility, a S...
متن کاملA novel role for the SUMO E3 ligase PIAS1 in cancer metastasis
Tumor metastasis contributes to the grave morbidity and mortality of cancer, but the mechanisms underlying tumor cell invasiveness and metastasis remain incompletely understood. Here, we report that expression of the SUMO E3 ligase PIAS1 suppresses TGFβ-induced activation of the matrix metalloproteinase MMP2 in human breast cancer cells. We also find that knockdown of endogenous PIAS1 or inhibi...
متن کاملCancer metastasis at a glance: A brief view of Breast Cancer Brain Metastasis
Cancer initiation and progression is a challenging scenario through developmental processes, which may be more complicated by occurrence of metastasis. Basically, diverse genetic alterations, including mutations, formation of truncated proteins and related pathways play key roles either in diagnosis or the most influential therapeutic purposes. ...
متن کاملProtein modification by SUMO.
Small ubiquitin-related modifier (SUMO) family proteins function by becoming covalently attached to other proteins as post-translational modifications. SUMO modifies many proteins that participate in diverse cellular processes, including transcriptional regulation, nuclear transport, maintenance of genome integrity, and signal transduction. Reversible attachment of SUMO is controlled by an enzy...
