Cleaved-Notch2 (Ala1734) Antibody - #AF5255

Fig. 3 Gm364 is essential for Notch2 activation. A Immunoprecipitation with control IgG and Gm364 antibody was performed and followed by SDS-PAGE and silver staining. Then distinct bands were sent for MALDI. TTC37, MIB2, and GRAMD1A were identified as Gm364-interacting proteins. B RT-PCR showed that within oocytes, Notch2 is the most abundant among Notch family members 1–4. C Immunofluorescence showed that Notch2 was enriched on the oocyte membrane. DNA in blue, Notch2 in green. D Western blot showed that Notch2 is more abundant in oocytes than in granular cells. E Co-IP and blots showed that Gm364 interacts with Notch2 in oocytes. F. Western blot showed that NICD2 was more abundant in oocytes than in granular cells. G Blot showed that NICD2 protein levels decreased gradually during oocyte meiosis. H–J Immunofluorescence and blot showed that Gm364 knockout significantly decreased the NICD2 protein level. DNA in blue, NICD2 in green. K Blot showed that γ-secretase inhibition significantly decreased NICD2 levels. L. NICD2 reduction by γ-secretase inhibition greatly decreased the percentage of MII oocytes. M, N Immunofluorescence of in vitro fertilized oocytes and quantification showed that inhibiting γ-secretase significantly decreased the percentage of fertilized oocytes and the percentage of 2-PN (two pronucleus). PNs in the control oocyte or chromosomes in the γ-secretase-inhibited (γ-secretase(-)) oocytes were delineated with red dot-line circle; polar bodies (pbs) were labeled with arrows. DNA in blue, tubulin in green. β-actin or α-tubulin was used as a loading control. Scale bar, 20 μm. *Indicates p < 0.05.
