Comments
STRADα is a pseudokinase that consists of a STE20-like kinase domain but lacks several critical catalytic residues. STRADα forms a ternary complex with MO25 and LKB1, which is a serine/threonine kinase that can activate 13 protein kinases. Dorfman et al. showed that at steady state, STRADα localizes predominantly to the cytoplasm. It diffuses to the nucleus but is actively exported by CRM1 through two NESs. The presence of one NES can facilitate the export of LKB1. A homozygous partial deletion in the STRADα, truncating 180 residues from the C-terminal, causes a severe human developmental and epileptic syndrome (PMSE).

Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus.
Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb
by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
