IGBP1 Associated to surface IgM-receptor; may be involved in signal transduction. Involved in regulation of the catalytic activity of the phosphatases PP2A, PP4 and PP6 by protecting their partially folded catalytic subunits from degradative polyubiquitination until they associate with regulatory subunits. Belongs to the IGBP1/TAP42 family. Ubiquitously expressed with highest levels in heart, skeletal muscle and pancreas. Note: This description may include information from UniProtKB.
