Enables mitogen-activated protein kinase binding activity and ribosomal protein S6 kinase activity. Involved in several processes, including learning; negative regulation of cell differentiation; and negative regulation of signal transduction. Located in several cellular components, including neuromuscular junction; perikaryon; and presynapse. Is expressed in adult head. Used to study Coffin-Lowry syndrome. Human ortholog(s) of this gene implicated in Coffin-Lowry syndrome; intellectual disability; and non-syndromic X-linked intellectual disability 19. Orthologous to several human genes including RPS6KA1 (ribosomal protein S6 kinase A1); RPS6KA2 (ribosomal protein S6 kinase A2); and RPS6KA3 (ribosomal protein S6 kinase A3).
FB Description
Ribosomal protein S6 kinase II (S6kII) encodes a protein that functions as a downstream effector and regulator of the MAP kinase pathway. It is involved in MAP kinase regulated developmental processes, organization of the neuromuscular junction and adult behavior including circadian rhythm and learning.
