In order to activate transcription, the NH2-terminal domain of the SREBP must be released from the membrane so that it can enter the nucleus. This release has been studied most extensively for one of the SREBPs, namely, SREBP-2. However, the mechanism appears to be similar for the other SREBPs (SREBP-1a and -1c) (1). Release of the NH2-terminal domain is accomplished by a two-step proteolytic event that is regulated by sterols (3). In sterol-depleted mammalian cells, this proteolysis is initiated by the Site-1 protease (S1P), which cleaves human SREBP-2 between the Leu522-Ser523 bond in the sequence RSVL S (4). This cleavage requires formation of a complex between SREBP and SCAP, a polytopic membrane protein of the ER, and it is prevented when this complex is disrupted

Using in vitro kinase assays, we found that active AMPK and Aurora B phosphorylated KIF4A at Ser801 and Thr799 respectively in a time-dependent manner (Figure 5D). KIF4A is phosphoregulated by AMPK and Aurora B. Although AMPK phosphorylation increased the ATPase activity of KIF4A, Aurora B phosphorylation resulted in a stronger increase (Figure 5I), which might be consistent with the more powerful kinase function of Aurora B during mitosis.

QRICH1 promotes the expression of translation-related genes. our combined ChIP-seq and RNA-seq analyses identified that QRICH1 and ATF4 were enriched at the promoters of these specific tRNA synthetases, and that ER stress positively regulated their transcription (Fig. 4I). Together, these findings suggest that QRICH1 and ATF4 modulate tRNA metabolic processes to promote secreted protein synthesis during ER stress.

These results suggest that PTH regulates Na(+),K(+)-ATPase by PKC and ERK-dependent alpha(1)-subunit phosphorylation and that the phosphorylation requires the expression of a serine at the 11 position of the Na(+),K(+)-ATPase alpha(1)-subunit.

Instead, AIP4 promotes the endocytosis of TRPV4 and decreases its amount at the plasma membrane.

Site‐directed mutagenesis of the SGK1 phosphorylation sites in the Nedd4‐2 protein (S382A,S468ANedd4‐2) and in the EAAT1 protein (T482AEAAT1, T482DEAAT1) significantly blunts the effect of S422DSGK1. Introduction of a negative charge at the SGK phosphorylation site in the EAAT1 protein leads to a strong stimulation of the carrier, whereas replacement with alanine markedly decreases the EAAT1‐mediated current. These observations suggest that SGK1 exerts its effect not only by phosphorylation of Nedd4‐2 but also by phosphorylation of EAAT1.

We show here that Cdc2 kinase phosphorylates the serines located in or near the nuclear localization signal (NLS) of hum an RCC1, the nucleotide exchange factor for Ran. This phosphorylation is necessary for RCC1 to generate RanGTP on mitotic chromosomes in mammalian cells, which in turn is required for spindle assembly and chromosome segregation. However, when both S2 and S11 were simultaneously mutated to As, the resulting 6His-RCC1S2,11A failed to be phosphorylated, whereas all of the other double mutants were phosphorylated (Fig. 1C). As expected, mutating all four sites to As (the 6His-RCC1S2,11,387A-T274A) also blocked phosphorylation (Fig. 1C).
