Phosphorylation of serine 13 is required for the proper function of the Hsp90 co-chaperone, Cdc37. | In this report, we demonstrate that mammalian Cdc37 is phosphorylated on Ser13 in situ in rabbit reticulocyte lysate and in cultured K562 cells and that casein kinase II is capable of quantitatively phosphorylating recombinant Cdc37 at this site.

For each receptor, we probed chimeric G alpha subunit activation via a transforming growth factor-alpha (TGF alpha) shedding response in HEK293 cells lacking endogenous Gq/11- and G12/13- signaling. | We defined positive coupling if any member of the subfamily scored LogRAi ≥ -1 and negative coupling if all of the members scored LogRAi < -1 (Figure 3A-B). ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0.

This interaction increases the polyubiquitylation of CKB and decreases total CKB levels within the cell. The targeting of CKB for degradation by Asb-9 was primarily SOCS box-dependent and suggests that Asb-9 acts as a specific ubiquitin ligase regulating levels of this evolutionarily conserved enzyme.

It was found that purified recombinant nNOS was phosphorylated by CaM-K Ialpha, CaM-K IIalpha, and CaM-K IV at Ser847 in vitro. Replacement of Ser847 with Ala (S847A) prevented phosphorylation by CaM kinases. Phosphorylated recombinant wild-type nNOS at Ser847 (approximately 0.5 mol of phosphate incorporation into nNOS) exhibited a 30% decrease of Vmax with little change of both the Km for L-arginine and Kact for CaM relative to unphosphorylated enzyme. The activity of mutant S847D was decreased to a level 50-60% as much as the wild-type enzyme. The decreased NOS enzyme activity of phosphorylated nNOS at Ser847 and mutant S847D was partially due to suppression of CaM binding, but not to impairment of dimer formation which is thought to be essential for enzyme activation.

Bioluminescence-based screening of small molecule modulators of the FGF14:Nav1.6 complex identified 4,5,6,7 -: tetrabromobenzotriazole (TBB), a potent casein kinase 2 (CK2) inhibitor, as a strong suppressor of FGF14:Nav1.6 interaction. Inhibition of CK2 through TBB reduces the interaction of FGF14 with Nav1.6 and Nav1.2 channels. Mass spectrometry confirmed direct phosphorylation of FGF14 by CK2 at S228 and S230, and mutation to alanine at these sites modified FGF14 modulation of Nav1.6-mediated currents.

Our observation that Cep215 may function downstream of pericentrin suggests that the two proteins affect centrosome cohesion through a common mechanism. |Finally, depletion of pericentrin caused an almost complete loss of Cep215 from centrosomes, a detectable reduction in centrosomal levels of Cep68 and rootletin, but no significant effect on C-Nap1 (Fig. 6C and Table 1). Taken together, these results point to functional (and perhaps molecular) interactions between (1) Cep68 and rootletin and (2) Cep215 and pericentrin.

CCL5, also known RANTES (regulated on activation, normal T cell expressed and secreted), is a potent chemoattractant for a variety of leukocytes, including T cells, mono- cytes, NK cells, and basophils, signaling via the CCR1, CCR3, and CCR5 cell surface receptors [59]. Among these receptors, CCL5 has the highest affinity for CCR5.

Mass spectrum analysis was employed after an in vitro kinase assay in which cells were incubated with or without ERK1-active kinase, and the results demonstrated that Sox2 was phosphorylated by ERK1 directly at S251, which was further verified by western blotting for the specific antibody targeting S251 phosphorylated Sox2 after the in vitro kinase assay.|Mechanistically, ERK1 kinase promoted autophagic degradation of Sox2 via phosphorylation of Sox2 at Ser251 and further SUMOylation of Sox2 at Lys245 in non CSCs.

ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0.

These results suggest that the region of GRASP‐1 downstream of the Caspase‐3‐cleavage site is capable of activating the JNK signaling pathway by enhancing the phosphorylation of JNK. these results suggest that full length GRASP‐1 does not enhance JNK pathway activity, possibly due to the inhibitory effect of the N‐terminal fragment on the C‐terminal fragment. In contrast, Caspase‐3 cleavage of GRASP‐1 releases the C‐terminal fragment, which in turn activates JNK signaling by serving as a scaffold protein.

Hsp90 chaperone cycle is tightly regulated by another group of proteins referred to as ‘co-chaperones'. Their stability does not depend on Hsp90 function but they interact with distinct Hsp90 conformational states, providing directionality to the Hsp90 cycle4. Furthermore, certain co-chaperones, such as HOP and Cdc37p50 inhibit the Hsp90 chaperone cycle, assisting in delivery of distinct sets of client proteins (steroid hormone receptors and kinases, respectively) to the Hsp90 chaperone machine.
