Knockdown of PAFAH1B2 strongly reduced Abeta secretion from human cells, and this effect was confirmed in primary cells derived from PAFAH1B2 knock-out mice
Title: Loss of PAFAH1B2 reduces amyloid-β generation by promoting the degradation of amyloid precursor protein C-terminal fragments.
Catalytic subunits of the Pafah1b complex, Pafah1b2 and Pafah1b3, specifically bind to the NPxYL sequence of VLDLR, but not to ApoER2.
Title: The Pafah1b complex interacts with the reelin receptor VLDLR.
study examined biochemical interactions of Pafah1b Alpha1 & Alpha2 subunits with the Reelin signaling machinery & demonstrated that Alpha2, but not Alpha1, binds Dab1 in a phosphorylation-independent manner

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
