Genes affected

PABIR1 (HGNC:23490): (PP2A Aalpha (PPP2R1A) and B55A (PPP2R2A) interacting phosphatase regulator 1) Enables protein serine/threonine phosphatase inhibitor activity. Involved in mitotic G2/M transition checkpoint; positive regulation of cell growth; and positive regulation of proteasomal ubiquitin-dependent protein catabolic process. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

PABIR1 links:

PIP5K1B (HGNC:8995): (phosphatidylinositol-4-phosphate 5-kinase type 1 beta) Predicted to enable 1-phosphatidylinositol-4-phosphate 5-kinase activity. Predicted to be involved in regulation of phosphatidylinositol 3-kinase signaling. Predicted to act upstream of or within phosphatidylinositol biosynthetic process. Located in uropod.
