OLC16 and OLC3 occupy similar positions to the two alkyl chains of the phospholipid PGV525 in 2DYR. The alkyl chain of OLC3 occupies a very similar position to the alkyl chain of the detergent LMT572 of 3HB3, while a portion of the detergent head group overlaps with the head groups of both OLC3 ... a phospholipid tail of PSC in 2DYR. Interestingly, this site does not exist in the structure of ba3: instead, the N-terminus of subunit II extends below the plane of the membrane and occupies the same region in space as the head groups of these lipids (Figure 3C). These examples, and the translation of OLC7 in cluster 5, represent ways in which lipid

The complex-glycosylated SLCO5A1 polypeptide is by far the most abundant SLCO5A1 species
Reduced BMP signaling results in hindlimb fusion with lethal pelvic/urogenital organ aplasia: a new mouse model of sirenomelia.
... the pelvic/urogenital organs of Bmp4 cKO mice. Bmp4 cKO mice had bladder aplasia, hypoplastic kidney, hypoplasia of external genitalia and anal stenosis (Fig. 2 B, D, F). These results suggest that disruption of Bmp4 function in caudal body regions phenocopies all prominent phenotypes of sirenomelia observed in humans. During mouse development, a transient embryonic ... Bmp4 cKO mice have both hindlimb fusion and defective pelvic/urogenital organs indicating that BMP4 is the critical ligand for caudal body development. Bmp7 KO mice do not show sirenomelia phenotypes (Fig. 6 B, F), but display kidney hypoplasia , ; implying possible functional redundancy of BMP signaling. Indeed, loss of a single copy of Bmp4 ... for pelvic/urogenital tissues. Normally, Bmp4 is expressed and BMP signaling is active in the aPCM during caudal body formation. Loss of pSMAD immunoreactivity in the aPCM region of Bmp4 cKO mice indicates that autocrine BMP4 action is required to form the aPCM. To investigate the role of BMP4 in the aPCM formation, we assessed apoptosis and cell proliferation
