Textbook Question
Chapter 6.7, Problem 3CC
MAKE CONNECTIONS Ø The polypeptide chain that makes up a tight junction weaves back and forth through the membrane four times, with two extracellular loops, and one loop plus short C-terminal and N-terminal tails in the cytoplasm. Looking at Figure 5.14, what would you predict about the amino acid sequence of the tight junction protein?

25. Your friend works in a cell biology research lab. She is working
she calls p125, because its molecular mass is 125 kiloDaltons. She knows that
p125 is a transmembrane protein with three membrane-spanning domains. It has
been previously reported that p125 interacts with three other proteins called p175,
p80, and p50 (again,
polyacrylamide gel). These four proteins
in the cell. To determine how these proteins interact with the membrane, you
perform a set of experiments in which you first lyse the cells and save some of
your lysate, which you run in the input lane (labeled "I" in Figure Q25 below).
The lysate is then subjected to a low-speed centrifugation so that you separate out
the membrane fraction (which ends up in the pellet, "P") from the cytoplasm
(which is in the supernatant, "S"). You then wash the pellet from the first
extraction with a high-salt wash that does not disrupt the lipid bilayer, and save a
little bit to run on the gel. After the high-salt wash, you centrifuge…

In general, how specifically would a missense mutation affect the KV1.1 protein?arrow_forwardChoose the statements that describe how the helix orients in the tertiary structure of an integral membrane protein. The threonine residues act as membrane interface anchors, interacting with the lipid bilayer and the aqueous environment. The amphipathic helix interacts with the lipid bilayer along its hydrophobic surface, exposing its hydrophilic surface to the aqueous environment. A group of helices cluster with their polar surfaces in contact with one another and their hydrophobic surfaces facing the lipid bilayer. The peptide entirely embeds in the lipid bilayer.
