Consensus phosphorylation sites for p42/44 MAPK and GSK-3 are present in the SP repeat of MCIP1 at serine 112 and serine 108, respectively |Several endogenous proteins are capable of inhibiting the catalytic activity of calcineurin. Modulatory calcineurin interacting protein 1 (MCIP1) is unique among these proteins on the basis of its pattern of expression and its function in a negative feedback loop to regulate calcineurin activity. Here we show that MCIP1 can be phosphorylated by MAPK and glycogen synthase kinase-3 and that phosphorylated MCIP1 is a substrate for calcineurin.

Here we systematically quantified ligand-induced interactions between 148 GPCRs and all 11 unique G alpha subunit C-termini. 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.

We have studied the relationship between the phosphorylation oftau by several kinases (MARK, PKA, MAPK, GSK3) and its assembly into PHFs. By contrast, MARK and PKA phosphorylate several sites within the repeats (notably theKXGS motifs including Ser262, Ser324, and Ser356, plus Ser320); in addition PKA phosphorylates somesites in the flanking domains, notably Ser214. This type of phosphorylation strongly reduces tau’s affinityfor microtubules, and at the same time inhibits tau’s assembly into PHFs.

To better understand how KIF1A-driven dense core vesicle (DCV) transport is regulated, we identified the KIF1A interactome and focused on three binding partners, the calcium binding protein calmodulin (CaM) and two synaptic scaffolding proteins: liprin-α and TANC2. We showed that calcium, acting via CaM, enhances KIF1A binding to DCVs and increases vesicle motility. In contrast, liprin-α and TANC2 are not part of the KIF1A-cargo complex but capture DCVs at dendritic spines. we can conclude that TANC2 and liprin-α are enriched in dendritic spines and interact with various synaptic proteins. TANC2 and Liprin-α2 Act as Immobile Postsynaptic Posts Able to Recruit KIF1A in a Subset of Dendritic Spines

Another substrate is the Rab8 guanine nucleotide exchange factor (GEF) Rabin8 (a Sec2p homolog) which we find is involved in spine synapse formation.

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.
