During mitosis, cdk1 phosphorylates hbo1 on thr-85/88, creating a docking site for plk1 to be recruited. Significantly, the overexpression of hbo1 mutated at the plk1 phosphorylation site (s57a) leads to cell-cycle arrest in the g1/s phase, inhibition of chromatin loading of the minichromosome maintenance (mcm) complex, and a reduced dna replication rate.

P28482	P49815	1	phosphorylation	down-regulates activity	0.681	Here, we show that Erk may play a critical role in TSC progression through posttranslational inactivation of TSC2. Erk-dependent phosphorylation leads to TSC1-TSC2 dissociation and markedly impairs TSC2 ability to inhibit mTOR signaling, cell proliferation, and oncogenic transformation. \|Serine to alanine substitution at S664 or double S664A/S540A mutagenesis resulted in a marked reduction in TSC2 phosphorylation to a similar extent. In contrast, S540A substitution only moderately impaired TSC2 phosphorylation (Figure 3D), corroborating the notion that in vivo S664 is the most relevant residue for Erk-mediated phosphorylation.

The identity of peptide T1 is unknown. These experiments established that the SAPK3/p38γ substrate was CapZIP. Using this antibody, we showed by immunoblotting that bacterially expressed CapZIP was phosphorylated at Ser-108 by SAPK4/p38δ, JNK1α1 and ERK2 in vitro, as well as by SAPK3/p38γ (results not shown). An important clue to the function of CapZIP and its phosphorylation came from the finding that it binds to the actin-capping protein CapZ (Figure 7A), and that cellular stresses trigger the dissociation of these two proteins (Figure 7B).Such an effect is presumably lost when CapZIP is phosphorylated and dissociates from CapZ.

Peptide T2 was sequenced and shown to comprise residues 79–112 of CapZIP, phosphorylated at Ser-108 (Figure 2B). The identity of peptide T1 is unknown.

Using this antibody, we showed by immunoblotting that bacterially expressed CapZIP was phosphorylated at Ser-108 by SAPK4/p38δ, JNK1α1 and ERK2 in vitro, as well as by SAPK3/p38γ (results not shown). An important clue to the function of CapZIP and its phosphorylation came from the finding that it binds to the actin-capping protein CapZ (Figure 7A), and that cellular stresses trigger the dissociation of these two proteins (Figure 7B).Such an effect is presumably lost when CapZIP is phosphorylated and dissociates from CapZ.

Hctps2 ser(568) was phosphorylated by casein kinase 1 both in vitro and in vivo. Mutation of ser(568) (s568a) significantly increased hctps2 activity, demonstrating that ser(568) is a major inhibitory phosphorylation site.

Itch regulates p45/NF-E2 in vivo by Lys63-linked ubiquitination| Interestingly, Itch suppressed the transactivation activity of p45/NF-E2 by adding a Lys63-linked polyubiquitin chain. Confocal microscopy revealed that ubiquitinated p45/NF-E2 became localized in the cytoplasm when Itch was over-expressed. Thus, Itch-mediated ubiquitination of p45/NF-E2 does not target the protein for proteasomal degradation, but instead retains p45/NF-E2 in the cytoplasm, where it cannot function as a transactivator.

Neuronal ELAV (nELAV) proteins are RNA-binding proteins which play a physiological role in controlling gene expression in memory formation, and their alteration may contribute to cognitive impairment associated with neurodegenerative pathologies such as Alzheimer's disease (AD). The experiments show for the first time that ADAM10mRNA represents a nELAV target and that these RNA-binding proteins can play a role in the post-transcriptional regulation of ADAM10 expression. nELAV proteins specifically bind the ADAM10 mRNA and this binding is disrupted following Aβ exposure

We demonstrate here that tuberin is phosphorylated on s939 and t1462 in response to pi3k activation. Our results are consistent with akt being the pi3k-depen-dent tuberin kinase. The pi3k-akt-mediated phosphorylation of tuberin would inhibit the function of the tuberin-hamartin complex.

Moreover, we demonstrate that ERK5 facilitates Chk1 phosphorylation induced by IR.|Since we have found that ERK5 was able to accelerate the phosphorylation and activation of IR-induced Chk1, therapeutic targeting of Chk1 in NSCLC cells with high ERK5 expression might be an effective strategy for overcoming radioresistance.

PKG phosphorylated TRPC6, and both T70 and S322 were targeted. Both sites were functionally relevant, as 8Br-cGMP strongly suppressed current in wild-type TRPC6 channels, but not in those with phospho-silencing mutations (T70A, S322A or S322Q).

A major kinase for GPCR‐induced CPI‐17 phosphorylation is PKC which is activated by the PLCbeta‐produced signaling messenger diacylglycerol (DAG). It phosphorylates CPI‐17 at Thr38 residue that directly docks at the active site of MLCP, thereby inhibiting its activity and promoting an increase of phosphorylation of myosin and of other MLCP.

Tec family protein tyrosine kinases (TFKs) play a central role in hematopoietic cellular signaling. Initial activation takes place through specific tyrosine phosphorylation situated in the activation loop.The major phosphorylation sites were identified as conserved tyrosines, for Itk Y180 and for Bmx Y215, both sites being homologous to the Y223 site in Btk
