High impact information on FAM12A

  • They also differ in content with the EP3A containing 9 serine and threonines in its carboxyl terminus and the EP3E none [1].
  • 2. Three of these variants, i.e. the EP3A, EP3E and EP3D, share the same primary amino acid sequence except for their carboxyl termini, which diverge from one another at the same point, approximately 10 amino acids away from the end of the seventh membrane spanning domain of the receptor [1].
  • Using a reporter gene assay, as a measure of intracellular cyclic AMP levels, the EP3A coupled more efficiently to the inhibition of adenylyl cyclase than did the EP3E [1].
  • In crude lysates of COS-7 cells transfected with the human EP3A, 1 microM PGE2 stimulated MAP kinase activity approximately 1.3-fold with an EC50 of approximately 6 nM [2].
  • More detailed sequence and PCR analysis identified two different but homologous gene transcripts, HE3 alpha and HE3 beta [3].
 

Anatomical context of FAM12A

 

Associations of FAM12A with chemical compounds

  • This activation of MAP kinase activity by the EP3A receptor may explain the proliferative actions of PGE2 in some tissues [2].
