Transmembrane protein 147 (TMEM147) is a novel component of the Nicalin-NOMO protein complex.

ABSTRACT: Nicastrin and its relative Nicalin (Nicastrin-like protein) are both members of larger protein complexes, namely gamma-secretase and the Nicalin-NOMO (Nodal modulator) complex. The gamma-secretase complex, which contains Presenilin, APH-1, and PEN-2 in addition to Nicastrin, catalyzes the proteolytic cleavage of the transmembrane domain of various proteins including the beta-amyloid precursor protein and Notch. Nicalin and its binding partner NOMO form a complex that was shown to modulate Nodal signaling in developing zebrafish embryos. Because its experimentally determined native size (200-220 kDa) could not be satisfyingly explained by the molecular masses of Nicalin (60 kDa) and NOMO (130 kDa), we searched in affinity-purified complex preparations for additional components in the low mo
