BMS 300 1st Edition Lecture 12 Outline of Last Lecture I Protein targeting to the endoplasmic reticulum protein translocator 1 secreted lyosomal proteins 2 transmembrane protein glycosylating in the ER II Cells functioning in concert tissues 1 group of similar cells performing similar functions III Types epithelia connective muscle nervous IV Epithelia form borders interfaces V Characteristics of Epithelia continuous layer of cells These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute attached to basal lamina oriented cells able to replicate cell functions VI Epithelia junctions Outline of Current Lecture VII Cell junctioning in epithelia anchoring 1 hemidesosomes basal lamina integrin 2 desmosomes cell to cell cadherin occluding 1 tight communicating GAP 1 connexons composed of 6 connexins VIII Glandular epithelium exocrine duct gland surface duct secretory adenocarcinoma IX Connective tissue scattered cells connected by the extracellular matrix they secrete connective tissue proper 1 fibrocytes cartilage 1 chondrocytes bone 1 osteocytes blood 1 hematopoietic stem cells X Skin as an organ epidermis Current Lecture Anchoring Junctions Two types of anchoring junctions 1 hemidesmosomes anchors epitheliac cells to the underlying extracellular proteins 2 desmosomes when you add the transmembrane proteins they form tight junctions which prevent movement within the gaps of the cells tight junctions are also occluding junctions there s a cadherin that ties the two cells together Keratin intermediate filament protein Integrin s extracellular secreted proteins of the basal lamina there is also a GAP junction this is a communicating junction you need to have proteins to anchor things to the basal lamina the gap junction has protein bridges which extend across gap junctions and they form a channel between the cells also called a cytoplasmic bridge for cytoplasmic continuity they
