Among the sites identified, only six were previously suggested to be the targets for specific kinases using in silico and/or in vitro analyses: S36 and S525 were attributed to the regulation by PKA; S484 and S664 were assigned to the serum- and glucocorticoid-inducible kinase 3 (SGK3); and S516 and S571 were ascribed to CaMKII (reviewed in Marionneau and Abriel, 2015). In marked contrast, several previously described phosphorylation sites were not detected in the present study, including the PKA-dependent S528, the CaMKII-associated T594, the PKC-dependent S1506, the adenosine monophosphate–activated protein kinase (AMPK)–dependent T101 (Liu et al., 2019), and the six Fyn-dependent tyrosines (Ahern et al., 2005; Iqbal et al., 2018).|The simplest interpretation of these findings is that these three phosphorylation clusters, at positions S457-S460, S483-T486, and S664-S671, are likely involved in regulating the basal and/or gating properties of native cardiac NaV1.5 channels. Conversely, the other phosphorylation sites, with lower stoichiometries, may play spatially or temporally distinct roles in the physiological or more pathophysiological regulation of channel expression or gating. | Remarkably, this MS analysis also revealed that the vast majority of identified phosphorylation sites (at least 26) are clustered, suggesting concomitant phosphorylation and roles in regulating channel expression and/or function. Unexpectedly, however, except for S664, S667, and S671, no apparent effects of phosphomimetic or phosphosilent mutations were observed on heterologously expressed (in HEK-293 cells) NaV1.5

PAKs specifically phosphorylate Ser15 of the sortilin-cd and alter its trafficking. It can be concluded that PAK1-3 may indeed instigate the phosphorylation of sortilin and that they target a single serine residue (Ser15) located in the kinase domain-binding site of the sortilin-cd. Full-length sortilins with the serine at position 793 (residue 15 in the cytoplasmic domain) (for the sequence, see Fig. 2). Phosphorylation (Ser15) downregulates the sortilin–AP-1 interaction.

We now demonstrate that amino acids 1-92 of hPPARalpha contain an activation function (AF)-1-like domain, which is further activated by insulin through a pathway involving the mitogen-activated protein kinases p42 and p44. Further analysis of the amino-terminal region of PPARalpha revealed that the insulin-induced trans-activation occurs through the phosphorylation of two mitogen-activated protein kinase sites at positions 12 and 21, both of which are conserved across evolution.

ZNF804A has been implicated in susceptibility to schizophrenia by several genome-wide association studies (GWAS), follow-up association studies and meta-analyses. ZNF804A was identified as a schizophrenia-associated gene by GWAS and was predicted to play a role in DNA binding and transcription To identify the genes that are affected by ZNF804A, we manipulated the expression of the ZNF804A protein in HEK293 human embryonic kidney cell lines and performed a cDNA microarray analysis followed by qPCR. We found that ZNF804A-overexpression up-regulated four genes (ANKRD1, INHBE, PIK3AP1, and DDIT3) and down-regulated three genes (CLIC2, MGAM, and BIRC3).

TGFbeta signals are transmitted via a cell surface receptor complex consisting of the TGFbeta type I receptor (TbetaRI) and TGFbeta type II receptor (TbetaRII).

All eight members of the FAM83 family (FAM83A–H) interacted with the α and α-like isoforms of CK1; FAM83A, -B, -E, and -H also interacted with the δ and ε isoforms of CK1. The intrinsic catalytic activity of CK1 is not affected by or required for the association of CK1 with FAM83 proteins. Our findings imply that the DUF1669 domains of FAM83 proteins anchor CK1 α, α-like, δ, and ε isoforms in specific subcellular compartments and potentially mediate their association with substrates.

SCP1 Dephosphorylates Smad2/3 in the Linkers|MAPK-mediated linker phosphorylation appears to have a dual role in Smad2/3 regulation. Mitogens and hyperactive Ras result in extracellular signal-regulated kinase (ERK)-mediated phosphorylation of Smad3 at Ser-204, Ser-208, and Thr-179 and of Smad2 at Ser-245/250/255 and Thr-220. Mutation of these sites increases the ability of Smad3 to activate target genes, suggesting that MAPK phosphorylation of Smad3 is inhibitory (11, 12). However, in contrast, ERK-dependent phosphorylation of Smad2 at Thr-8 enhances its transcriptional activity
