DORSAL VENTRAL AXIS FORMATION IN DROSOPHILA(PART-4) |CSIR NET |DEVELOPMENTAL BIOLOGY

WELCOME TO TEACHING PATHSHALA!!
TOPIC-DORSAL VENTRAL AXIS FORMATION IN DROSOPHILA(PART-4) |CSIR NET |DEVELOPMENTAL BIOLOGY
D-V polarity established by the gradient of a transcription factor called Dorsal.Dorsal protein synthesize in cytoplasm.Translocation of dorsal into the nuclei of ventral cells will help in ventralization of embryo.Dorsal gene will produce Dorsal protein and this protein will help in formation of ventral axis of embryo.Dorsal protein distinguish dorsal and ventral side.
GURKEN-Signal the dorsalization.Garken mRNA is synthesize in oocytes and it produce gurken protein with has affinity to bind with Torpedo receptor. Gurken protein remain in dorsal side.
TORPEDO-Receptor present in follicle cells and it bind to gurken.
CACTUS-cactus remain bound to Dorsal in a cytoplasm. After the phosphorylation of cactus, it release the Dorsal so that dorsal can enter the nucleus for its ventralization activity.
ABOUT THIS CHANNEL ---This channel will have the syllabus wise lectures Video for CSIR-NET-Life science /GATE-Lifescience/BARC/ICMR-JRF/ICAR.
