Q8TBB1	Q05586	1	ubiquitination	down-regulates quantity by destabilization	0.288	We used the Ligand of Numb protein X (LNX) family of E3s, a group of PDZ domain-containing RING-type E3 ubiquitin ligases, to demonstrate the feasibility of this strategy. Many potential substrates of LNX E3s were identified. Eight of the nine selected candidates were ubiquitinated in vitro, and two novel endogenous substrates, PDZ-binding kinase (PBK) and breakpoint cluster region protein (BCR), were confirmed in vivo.

AKT positively regulates cyclin D1 expression through inactivation of glycogen synthase kinase 3_ (GSK3_). The AKT-mediated phosphorylation of glycogen synthase kinase 3_ on serine9 decreases its kinase activity for Thr286 of cyclin D1, which inhibits the nuclear export and the cytoplasmic proteasomal degradation of cyclin D1	SIGNOR-245420
P17252	P19429	1	phosphorylation	up-regulates activity	0.343	In addition to the established phosphorylation sites (S22 and S23) we found that S38 and S165 were the other two main sites of phosphorylation. \| Phosphorylation of S22/23A also decreased its affinity for troponin C indicating that phosphorylation of S38 and/or S165 impedes binding of troponin I to troponin C. Formation of a troponin I/troponin C complex prior to cAMP-dependent protein kinase treatment did not prevent overphosphorylation.	SIGNOR-249066
P07550	Q9H6Z9	0	hydroxylation	up-regulates quantity by stabilization	0.318	We further show that the interaction of pVHL with beta(2)AR is dependent on proline hydroxylation (proline-382 and -395) and that the dioxygenase EGLN3 interacts directly with the beta(2)AR to serve as an endogenous beta(2)AR prolyl hydroxylase. Under hypoxic conditions, receptor hydroxylation and subsequent ubiquitylation decrease dramatically, thus attenuating receptor degradation and down-regulation.	SIGNOR-262007

P01178	Q92824	0	cleavage	down-regulates quantity	0.248	Oxytocin-extended form is further cleaved by enzymatic activity to yield the nine-amino-acid active peptide, OT. The proteolysis may involve several pro-hormone convertases, convertase 2 (PC2) (20p11-1-11.2) and convertase 5 (PC5) (9q21.3) (Gabreels et al 1998). Both enzymes are found in OT neurosecretory vesicles and are a part of a family of subtilisen/kexinlike convertases (Seidah et al 1994). It is a product of the OT gene located at human gene locus 20p13 (Rao et al 1992). The processing cascade results in the production of neurophysin I and OT extended form (OT-X), which is OT with a C-terminal, three-amino-acid extension.	SIGNOR-270327

Q969F2	Q96BH1	0	polyubiquitination	down-regulates quantity by destabilization	0.451	Here, we show that Naked2 is a short-lived protein with a half-life of 60 min caused by its rapid ubiquitin-mediated proteasomal degradation. Overexpression of TGF-alpha stabilizes Naked2 protein in an EGF receptor (EGFR)-independent manner; a physical interaction between the cytoplasmic tail of TGF-alpha and Naked2 is necessary and sufficient for this protection. We have identified a RING finger protein, AO7/RNF25, as a ubiquitin ligase for Naked2, and we have shown that overexpression of TGF-alpha reduces binding of AO7 to Naked2.	SIGNOR-271738

Q9UH99	P02545	0	relocalization	up-regulates activity	0.622	In the case of Sun2, there is some evidence that A-type lamins might contribute to Sun2 localization in the INM. We report that an interaction between subunits of the HOPS complex and the ERM (ezrin, radixin, moesin) proteins is required for the delivery of EGF receptor (EGFR) to lysosomes. Inhibiting either ERM proteins or the HOPS complex leads to the accumulation of the EGFR into early endosomes, delaying its degradation.	SIGNOR-261310

P09238	P10915	1	cleavage	down-regulates quantity by destabilization	0.323	Matrix metalloproteinases cleave at two distinct sites on human cartilage link protein. Sequencing studies of modified link protein components revealed that stromelysins-1 and -2, gelatinases A and B and collagenase cleaved specifically between His16 and Ile17, and matrilysin, stromelysin-2 and gelatinase A cleaved between Leu25 and Leu26. Based on previously determined in situ cleavage sites it is evident that matrix metalloproteinases are not solely responsible for the accumulation of link protein degradation products in adult human cartilage, indicating that additional proteolytic agents are involved in the normal catabolism of human cartilage matrix.

Taken together, these results suggest that TRB3 may promote loss of fat by mediating the COP1-dependent ubiquitination and inactivation of ACC. Taking these results together, we propose that TRB3 may protect against diet-induced obesity by stimulating fatty acid oxidation in adipose during fasting through the COP1-mediated ubiquitination and degradation of ACC (Fig. 4D).

Furthermore, the two enzymes cleaved COMP in a distinctive manner, generating a major proteolytic product of 60 kDa. Our results suggest that MMP-19 may participate in the degradation of aggrecan and COMP in arthritic disease, whereas MMP-20, due to its unique expression pattern, may primarily be involved in the turnover of these molecules during tooth development.

In the case of Sun2, there is some evidence that A-type lamins might contribute to Sun2 localization in the INM. We report that an interaction between subunits of the HOPS complex and the ERM (ezrin, radixin, moesin) proteins is required for the delivery of EGF receptor (EGFR) to lysosomes. Inhibiting either ERM proteins or the HOPS complex leads to the accumulation of the EGFR into early endosomes, delaying its degradation.
