Predicted to enable protein phosphatase 2A binding activity. Acts upstream of or within protein dephosphorylation. Predicted to be located in cell projection; cytoplasm; and cytoskeleton. Predicted to be active in actin cytoskeleton. Is expressed in several structures, including alimentary system; axial musculature; orbito-sphenoid; urinary system; and vibrissa. Orthologous to human CTTNBP2NL (CTTNBP2 N-terminal like). [provided by Alliance of Genome Resources, Apr 2022]
