basic FUNCTION
  • phosphatidylinositol-4-phosphate-5 kinase, type 1 alpha, putatively involved in membrane ruffle formation
  • playing a role in regulating stress-induced apoptosis
  • activation of KIF2A is not sufficient but is essential for the function of PIP5K1A
  • PIP5K1A and PIP5K1B may coordinately and/or redundantly function in the maintenance of sperm number and morphology during spermatogenesis
  • cytosolic PIP5K1A has been implicated in several cellular events like endocytosis, membrane ruffling and migration; the nuclear pool has been shown to be involved in pre-mRNA splicing events

    protein
  • PIPSL is the fusion of phosphatidylinositol-4-phosphate 5-kinase (PIP5K1A) and 26S proteasome subunit (S5a/PSMD4) genes
  • suppressed the elongation of axon branches in a KIF2A-dependent manner, suggesting a unique PIPK-mediated mechanism controlling MT dynamics in neuronal development
  • cell & other
    REGULATION
    activated by the small G protein ADP-ribosylation factor ARF6
    Other nuclear PIP5K1A is modified by SUMO1 in normal cells
    modified by polySUMO-2 only during apoptosis
