CBL proteins interact with CIPK serine-threonine protein kinases. Binding of a CBL protein to the regulatory NAF domain of a CIPK protein lead to the activation of the kinase in a calcium-dependent manner.<ref>PMID:11006339</ref> <ref>PMID:10725350</ref> <ref>PMID:12034882</ref> | + | [https://www.uniprot.org/uniprot/NMT1_HUMAN NMT1_HUMAN] Adds a myristoyl group to the N-terminal glycine residue of certain cellular and viral proteins. |

Publication Abstract from PubMed
An organism's entire protein modification repertoire has yet to be comprehensively mapped. N-myristoylation (MYR) is a crucial eukaryotic N-terminal protein modification. Here we mapped complete Homo sapiens and Arabidopsis thaliana myristoylomes. The crystal structures of human modifier NMT1 complexed with reactive and nonreactive target-mimicking peptide ligands revealed unexpected binding clefts and a modifier recognition pattern. This information allowed integrated mapping of myristoylomes using peptide macroarrays, dedicated prediction algorithms, and in vivo mass spectrometry. Global MYR profiling at the genomic scale identified over a thousand novel, heterogeneous targets in both organisms. Surprisingly, MYR involved a non-negligible set of overlapping targets with N-acetylation, and the sequence signature marks for a third proximal acylation-S-palmitoylation-were genomically imprinted, allowing recognition of sequences exhibiting both acylations. Together, the data extend the N-end rule concept for Gly-starting proteins to subcellular compartmentalization and reveal the main neighbors influencing protein modification profiles and consequent cell fate.
