Words similar to dephosphorylation
Example sentences for: dephosphorylation
How can you use “dephosphorylation” in a sentence? Here are some example sentences to help you improve your vocabulary:
The dephosphorylation of phosphoproteins is universally catalyzed by protein phosphatases that are classified into two major functional groups, protein tyrosine phosphatase (PTP) and protein serine/threonine phosphatase (PP) although enzymes with various degrees of dual-specificity are also encountered [ 1 2 3 4 5 ] . The majority of Ser/Thr phosphatases belong to three classical groups, namely PP1, PP2A, and PP2B (calcineurin), and possess similar primary structures in their catalytic cores [ 2 3 6 ] . PP1, in particular, exhibits an extremely high degree of sequence conservation through evolution, and its orthologs and isoforms are found in all eukaryotic cells [ 6 7 ] . In various organisms, PP1 regulates such diverse cellular processes as cell cycle progression, protein synthesis, carbohydrate metabolism, transcription, and neuronal signaling [ 3 7 ] , underscoring its profound importance in biology.
The best characterized regulation of α-secretase processing typically involves protein phosphorylation via PKC [5,29] or ERKs [7] or protein dephosphorylation by protein phosphatase 1 or 2A [29].
Results suggested that SAHA induced cell growth arrest through dephosphorylation of three pRb pocket proteins, which may be related to inhibition in G1/S phase cdk activities.
For example, the stress kinase JNK1 was activated during TLK286 induced apoptosis [ 17 ] and JNK is known to be activated during apoptosis induced by a variety of stress stimuli [ 18 ] . However, in HL60/TLK286 resistant cells, we observed an overexpression of two phosphatases PP2 (AA599092) and MKP5 (AA056608) involved in JNK dephosphorylation and inactivation (Table 2).
In fact, dephosphorylation of moesin occurred in mouse epithelial MTD-1 cells during fixation in 1% or 4% paraformaldehyde at room temperature for 15 min [ 12].
