Unformatted text preview: e, iden2fy how proteins involved interact with one another and how they confer func2on For each type of cell junc2on, outline the proteins involved and func2on Compare and contrast how the different proteins involved in cell junc2ons confer cellular func2on Outline different proteins involved in the cytoskeleton Goal: to understand benefits/drawbacks of molecular biology techniques used to detect genes at the transcrip2onal and transla2onal level •  Given a specific problem, provide a technique that can be used to answer the ques2on •  Iden2fy the benefits and drawbacks of the molecular biology techniques discussed in lecture 5 Cell communica2on 6 Cell Signaling •  Cells need to be able to respond to environmental cues •  Cell signaling  ­ Cytoskeleton – Cellular movement h^p://www.youtube.com/watch?v=JnlULOjUhSQ 7 Signaling pathway •  A cell releases a signal (Signaling cell), which can be a small pep2de or a small molecule •  The signal binds to a receptor in an adjacent/ same cell (Responding cell) •  The receptor sends a signal to the intracellular region that will ac2vate a pathway that will change the expression of proteins inside the cell (signal transduc2on) •  This change will produce a response that will correspond to the s2mul...
