Post-translational modificationi

Phosphorylated at Ser-36 by PHK and PKC. Phosphorylation prevents interaction with Calmodulin and interrupts several learning- and memory-associated functions (By similarity).By similarity
Phosphorylation is activated by calcium, phospholipids, and diacylglycerol. Phosphorylation inhibits binding to calmodulin both in the presence and absence of calcium.2 Publications
Disulfide bond formation is redox-sensitive. The cysteine residues are readily oxidized by several nitric acid (NO) donors and other oxidants to form intramolecular disulfide. Cys-51 can form a disulfide with any other of the cysteine residues with an order of reactivity Cys-9 > Cys-4 > Cys-3.

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
