Our Ephexin-1 (C-terminal region) rabbit polyclonal primary antibody from PhosphoSolutions is produced in-house. It detects chicken, human, mouse, and rat Ephexin-1 (C-terminal region) and is antigen affinity purified. It is great for use in WB, ICC.
Western blot analysis of human A431 cells untreated (lanes 1 & 3) or treated with pervanadate (1 mM) for 30 min. (lanes 2 & 4). The blot was probed with anti-Ephexin-1 (C-terminal region) (lanes 1 & 2) and anti-Ephexin-1 (Tyr-87) (lanes 3 & 4).
The Eph family of receptor tyrosine kinases, and their ephrin ligands, are important for cell positioning and morphogenesis during development. EphA4 receptor can inhibit axon outgrowth and has roles in regulating axon projections during neural development. Eph signaling pathways require both receptor kinase activity and activation of Rho-GTPase guanine nucleotide-exchange factors (GEFs). Ephexin-1 is a Dbl family GEF that may be important for regulating Rho GTPase activity downstream of EphA4/FGFR complexes. EphA4 activation leads to Src kinase phosphorylation of Tyr-87 in ephexin-1, which enhances activation of RhoA, but not Rac1 or Cdc42. In addition, ephexin-1 also binds FGFRs, and is phosphorylated at Tyr-87, as well as other tyrosine sites.

Ephexin-1 synthetic peptide (coupled to carrier protein) corresponds to amino acids in the C-terminal region of mouse ephexin-1. This sequence has significant homology to the same region in human and rat ephexin-1, and has low homology to other known proteins.
