    text
  • NAA10 and NAA15 are both highly expressed in regions of cell division and migration during brain development
  • basic FUNCTION
  • acetyltransferase activity that may be important for vascular, hematopoietic and neuronal growth and development
  • having a function in the progression of papillary thyroid carcinomas
  • functional role for NAA15 in blood-vessel permeability dynamics that are crucial for vascular homeostasis
  • is an important regulator of retinal endothelial permeability and homeostasis by modulating a signaling pathway involving SRC and Cortactin
  • NAA15, a subunit of the N-terminal acetyltransferase NatA, complexes with the SRC substrate CTTN and supports adult retinal homeostasis through regulation of vascular permeability
  • role for NAA15 in development of the nervous system
  • CELLULAR PROCESS cell life, differentiation
    nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component non-catalytic component of the NATA N-terminal acetyltransferase, which is composed of ARD1A, NAT1 and NAT5 and catalyzing acetylation of proteins
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with NAA10 (NAA15 and NAA10 are cleaved during apoptosis, resulting in a decreased NAT activity)
  • associates with the acetyltransferase NAA10 and exerts an angiostatic function in adult retinal-blood-vessel homeostasis
  • association between NAA15 and CTTN, and NAA15 is involved in the regulation of retinal-endothelial-cell permeability to albumin
  • cell & other

    decrease in the level of expression of NAA15 in the retinal and choroidal vasculature during aging contributes to the multifactorial process that leads to the development of age-related retinopathy and choroidopathy

    ANIMAL & CELL MODELS
  • in mice, upregulated expression of Naa15 has been shown in regions of neuronal migration, and proliferation in the neonatal mouse brain has been shown along with reduced expression as neurons differentiate during early postnatal development
