Disease relevance of Tcfap2a_predicted

  • The 5' upstream region of the gene was characterized and some potential controlling elements for gene regulation, such as Sp-1, AP-2, and Hepatitis B virus enhancer, were found [1].
  • Other regions between -340 and 80 that bind proteins in the GH4C1 nuclear extracts include the major transcription initiation site, which has homology to the initiator sequence; the pituitary-specific transcription initiation sites (-101 and -105); and sequences with homology to NF-1, Pan-1, simian virus-40 enhancer core, and AP-2-binding sites [2].
  • Increases in AP-2 alpha and ATF-2 were sustained throughout the SON during water deprivation, suggesting that these transcription factors could play a role in the maintenance of VP and oxytocin gene transcription in response to dehydration [3].
  • High expression levels of AP-2 were observed in different cell types including mesangial cells of kidney samples from patients with proteinuria [4].
  • The results show that the cis-acting putative AP-2 site and the presence of serum are important in NHE-1 expression, whereas external acidosis had no direct effect on the promoter [5].

Associations of Tcfap2a_predicted with chemical compounds

  • In contrast, chronic administration of lithium-chloride (40 mg/kg) did not affect the amount of the two AP-2 isoforms [20].
  • Chronic administration of citalopram (10 mg/kg), imipramin (10 mg/kg) and lithium-chloride (40 mg/kg) significantly decreased DNA-binding activity of AP-2 [20].
  • The second pathway, however, uses AP2 instead of AP3 and is brefeldin A insensitive [15].
  • We have now cloned, sequenced, and overexpressed bovine alpha-COP, the 135-kD subunit of coatomer as well as delta-COP, the 57-kD subunit and have identified a yeast homolog of delta-COP by cDNA sequence comparison and by NH2-terminal peptide sequencing. delta-COP shows homologies to subunits of the clathrin adaptor complexes AP1 and AP2 [21].
  • This inhibition results from a reduction in phosphoinositide 4,5-bisphosphate levels which causes dissociation of AP2, clathrin, and dynamin from the plasma membrane [10].
