STE20/SPS1-related proline-alanine-rich protein kinase (Q9Z1W9 )

Uniprot ID Q9Z1W9
Protein Name STE20/SPS1-related proline-alanine-rich protein kinase
Gene Name Stk39
Species Mus musculus (Mouse)
Signal peptide(a) N Secretome P(b)
Function May act as a mediator of stress-activated signals. Mediates the inhibition of SLC4A4, SLC26A6 as well as CFTR activities by the WNK scaffolds, probably through phosphorylation (PubMed:21317537, PubMed:23542070). .

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
