Enables protein kinase binding activity. Predicted to be involved in several processes, including positive regulation of cold-induced thermogenesis; positive regulation of gene expression; and protein phosphorylation. Predicted to act upstream of or within nail development. Part of nucleotide-activated protein kinase complex. Orthologous to human PRKAB1 (protein kinase AMP-activated non-catalytic subunit beta 1).
