Function:Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathway. 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. ,similarity:Belongs to the 14-3-3 family. ,subcellular location:In neurons , axonally transported to the nerve terminals. ,subunit:Homodimer. Interacts with PCTK1 (By similarity) . Interacts with SSH1. Interacts with CDKN1B ('Thr-198' phosphorylated form) ; the interaction translocates CDKN1B to the cytoplasm. ,tissue specificity:Abundantly expressed in brain , heart and pancreas , and at lower levels in kidney and placenta. Up-regulated in the lumbar spinal cord from patients with sporadic amyotrophic lateral sclerosis (ALS) compared with controls , with highest levels of expression in individuals with predominant lower motor neuron involvement. ,
