We now show that human TFIIA is phosphorylated in vivo on serine residues that are partially conserved between yeast and human TFIIA large subunits. Alanine substitution mutation of serine residues 316 and 321 in TFIIA alphabeta reduced TFIIA phosphorylation significantly in vivo. Additional alanine substitutions at serines 280 and 281 reduced phosphorylation to undetectable levels. Mutation of all four serine residues reduced the ability of TFIIA to stimulate transcription in transient transfection assays with various activators and promoters, indicating that TFIIA phosphorylation is required globally for optimal function.

Taken together, these observations strongly support the notion that several different CDK-cyclin complexes are involved in the phosphorylation of Tob2 at S254.A more detailed regulatory context of Tob2 phosphorylation at S254 is provided by our findings from mass-spec and in vitro kinase analyses that suggest connections to PP2B and PP2C phosphatases and CDK-cyclin complexes, particularly CDK1, CDK2, and CDK4 (Table 1; Supplemental Table S2).One possibility is that the phosphorylation of S254 helps stabilize the interaction of Tob2 with the Ccr4–Not complex, which could contribute to Tob2's ability to recruit the entire Ccr4–Not complex and thus further enhances deadenylation.

Decreased expression of 4-hydroxyphenylpyruvic acid dioxygenase (HPD), a key enzyme for tyrosine metabolism, is a cause of human tyrosinemia. However, the regulation of HPD expression remains largely unknown. Here, we demonstrate that molecular chaperone TTC36, which is highly expressed in liver, is associated with HPD and reduces the binding of protein kinase STK33 to HPD, thereby inhibiting STK33-mediated HPD T382 phosphorylation. The reduction of HPD T382 phosphorylation results in impaired recruitment of FHA domain-containing PELI1 and PELI1-mediated HPD polyubiquitylation and degradation.

The r-snare vamp4, which contains a dileucine motif, binds to the ap-1 or the ggas. Serine 20 and leucines 25,26 are essential for this binding. Ap-1 association with vamp4 is enhanced when serine 30 is phosphorylated by casein kinase 2. This phosphorylation-dependent modulation of ap-1 binding is mediated by pacs-1 (phosphofurin acidic cluster sorting protein). Ablation of both the dileucine motif and serine 30 results in a dramatic mislocalization of vamp4 in the regulated secretory pathway.

Moreover, inhibition of TFII-I function in a B-cell line resulted in decreased heavy-chain transcript levels.| Figure 3 shows that both anti-Bright and anti-TFII-I precipitated the bf150 Bright binding site from the B-cell line but not from a T-cell line that contains but does not express the V1 gene.

As CD300b phosphorylation was occurring only in the presence of both c-Fyn and DAP-12, we addressed whether tyrosine phosphorylation was required for association of CD300b and DAP-12. For this purpose, we generated a set of HA-tagged CD300b mutants affecting the transmembrane lysine (K158L), the cytoplasmic tyrosine (Y188F) or both residues.|As expected, the CD300b double mutant could neither recruit DAP-12 nor become phosphorylated in the presence of c-Fyn kinase (Fig. 5⇑C). Association between CD300b and DAP-12 was maintained in absence of the c-Fyn kinase, indicating that phosphorylation of the adaptor was not essential for the formation of the complex (data not shown)

GRK2 and GRK6 coimmunoprecipitate with IGF-1R and increase IGF-1R serine phosphorylation, promoting β-arrestin1 association. Using immunoprecipitation, confocal microscopy, and FRET analysis, we demonstrated β-arrestin/IGF-1R association to be transient for GRK2 and stable for GRK6. Using bioinformatic studies we identified serines 1248 and 1291 as the major serine phosphorylation sites of the IGF-1R. Targeted mutation of S1248 recapitulates GRK2 modulation, whereas S1291 mutation resembles GRK6 effects on IGF-1R signaling/degradation
