Amyloid-like protein 1, also known as APLP1, is a protein that in humans is encoded by the APLP1 gene.[3][4] APLP1 along with APLP2 are important modulators of glucose and insulin homeostasis.[5]

Function[edit]

This gene encodes a member of the highly conserved amyloid precursor protein gene family. The encoded protein is a membrane-associated glycoprotein that is cleaved by secretases in a manner similar to amyloid beta A4 precursor protein cleavage. This cleavage liberates an intracellular cytoplasmic fragment that may act as a transcriptional activator. The encoded protein may also play a role in synaptic maturation during cortical development. Alternatively spliced transcript variants encoding different isoforms have been described.[3]

APLP1 and APLP2 double knockout mice display hypoglycemia and hyperinsulinemia indicating that these two proteins are important modulators of glucose and insulin homeostasis.[5]
