PTPRK and lipoma: C1ORF106 (C1 Orfan 106), ARHGAP31 (GTPase activating protein 31), LPP (lipoma-preferred partner) and PTPRK (protein tyrosine phosphatase receptor-type K) play roles in actin rearrangement in the cytoskeleton, in the cell‒cell adhesion process and in the maintenance of intestinal epithelial barrier function [63].
