Negatively regulates SHH signal transduction (By similarity). Probably functions in signal transduction from heterotrimeric G protein-coupled receptors. Binds to phosphorylated inositide lipids.
Expressed at high levels in testis, ovaries, thyroid, and spinal chord.
Belongs to the TUB family.
Nucleus. Cell membrane. Cell projection > cilium. Cytoplasm. Secreted. Does not have a cleavable signal peptide and is secreted by a non-conventional pathway (By similarity). Translocates from the plasma membrane to the nucleus upon activation of guanine nucleotide-binding protein G(q) subunit alpha.
