Primary structural Protein of mitotic spindle - gtmnath - ArchivalUser - 06-14-2006 Hi, There was a question on nbme form 2 as follows: I will appreciate if anyone can guide me about the correct answer Which of the following is the most likely primary structural protein of mitotic spindle? a. actin b. desmin c. myosin d. tubulin e. vimentin thanks 0 - ArchivalUser - 06-14-2006 I think DESMIN U can read whole topic from here http://www.web.virginia.edu/Heidi/chapter17/chp17frameset.htm 0 - ArchivalUser - 06-14-2006 D. tubulin 0 - ArchivalUser - 06-14-2006 The mitotic spindle is composed primarily of microtubules, a polymer of the protein tubulin. 0 - ArchivalUser - 06-14-2006 i think its tubulin. (victory1 isn't desmin the intermediate filament of muscles) 0 - ArchivalUser - 06-14-2006 actin-microfilament vimentin-vascular smooth muscle,fibroblasts desmin-smoothmuscle,skeletal & cardiac muscle myosin-skeletal muscle ans has to be tubulin 0 - ArchivalUser - 06-15-2006 i agree with tubulin too but here are some asides tumor markers 1 desmin muscle 2 cytokeratin epithelial 3 vimentin mesenchymal 4glialfibrillary acidic protein astrocyte tumor |
