Yeast specific lipids promote the transport of lipid transfer protein (LTP) across the blood brain barrier to the neurons that regulate systemic insulin signaling.
Biophysical binding and structural prediction studies reveal that Tetraspanin12 directly binds the ligand Norrin, in a manner that is negatively cooperative with Norrin-Fzd4 binding and competitive with Norrin-LRP5/6 binding.

The messenger RNA encoding La-related protein-4 (LARP4) contains a short region of instability whose codon clusters are sensitive to low abundance tRNAs that when elevated increase LARP4 activity for poly(A) lengthening of ribosomal protein mRNAs and other mRNAs.

In oligodendrocyte progenitor cells, lipid metabolism and peroxisome biogenesis are regulated by the low-density lipoprotein related-receptor-1, and if disrupted, impair proper white matter development and adult repair.

Cryo-EM structure of monomeric human Frizzled5 was determined with a universal fiducial antibody at 3.7 Å overall resolution, which supports a simple Fzd/LRP6 heterodimerization mechanism of canonical Wnt/β-catenin signaling.
Hypoplastic left heart syndrome is reflected by reduced proliferative capacity of patient iPSC-derived cardiomyocytes and requires the activity of LRP2/APOB proteins, likely in conjunction with SHH and WNT signaling pathways.

LARP4 protects mRNAs against deadenylation over a wide range of poly(A) lengths but with most apparent functional impact on short lengths known to sensitize PABP binding and mRNA stability.
Receptors for two distinct pathways are linked to choreograph the dynamic interaction of Wnt on the stem cell membrane, which leads to the control of asymmetric cell division.
