[https://www.uniprot.org/uniprot/1433Z_HUMAN 1433Z_HUMAN] Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner.<ref>PMID:9360956</ref> <ref>PMID:14578935</ref> <ref>PMID:15071501</ref> <ref>PMID:15644438</ref> <ref>PMID:16376338</ref> | |||

== Publication Abstract from PubMed == | |||
The serine/threonine protein kinase liver kinase B1 (LKB1) is a tumour suppressor and plays important roles in development and metabolism. It phosphorylates AMPK and AMPK-related kinases to regulate multiple physiological processes. Mutations in LKB1 often occur in multiple cancers. LKB1 can be suppressed by 14-3-3 proteins in a phosphorylation-dependent manner. Previously, the structure of a 14-3-3zeta-LKB1 fusion protein has been reported, revealing a phosphorylation-independent binding mode of LKB1 to 14-3-3 proteins. Here, the crystal structure of phosphorylated LKB1 peptide in complex with 14-3-3zeta was solved, which provides a structural basis for the phosphorylation-dependent recognition of LKB1 by 14-3-3 proteins. | |||
