BIO 1140 Lecture Notes - Lecture 6: Membrane Fluidity, Tight Junction, Cell Membrane
Document Summary
Capping protein (stops growth) & arch-23 complex protein allows protein to branch. From the centrosome to the outside of the cell. Yes it is: different layer additional to plasma membrane. Ecm is network/mesh of different types of protein: different features: part of proteoglycans (recognition & signalling) Fibronectin: anchors ecm and plasma membrane together: when cells are joined together/attached together, what are some of the ways to interact, use tight junctions (cell to interactions have many different subtypes) Interact two cells together & seal the cells together (fusing the membrane together in area) Ecm in area is compressed & tightened (basically not there: nothing can be sealed, anchoring junctions/desmosomes: intermediate filaments with plaques of proteins (e. g. keratin) forming junction between cells called desmosomes adherence junctions made of actin. Good for support/mechanical & shearing force (no exchange: gap junction: allow direct passage of small molecules.
