Nuclear proteins having a molecular mass more than approximately 40 KDa must be actively imported through nuclear pore complexes

. What is the name given to the stretch of amino acid sequence (located in the protein that needs to be transported) that allows the selective transport of proteins into the nucleus? Based on what we learned in the class, name three important proteins that are required for the import of proteins into the nucleus, and briefly describe how they function.

Answer:

Nuclear Localization Signal (NLS).

1. Importin

2. Nucleoporin

3. RanGTP

Explanation: The specific amino acid sequence motif that allows the selective transport of proteins having a molecular mass more than approximately 40 KDa into the nucleus is called Nuclear Localization Signal (NLS).

These proteins enter the nucleus through the Nuclear Pore Complex (NPC). The transit of the protein from the cytoplasm to the nucleus requires binding to a <u>receptor</u> called Karyopherin or Importin β, this receptor binds to the protein by <em>direct recognition of the NLS</em> sequence or through <em>an adapter </em>protein, Importin α (depending on the NLS sequence).

The passage of the complex through the NPC needs, in turn, the <em>binding of the </em><em>Importin </em><em>to the </em><em>Nucleoporins</em>, <u>proteins that form the nuclear pore</u>.

Once the complex passes through the pore, the <em>receptor-bound protein is released</em> <em>by the interaction</em> of Importin with RanGTP, an enzyme with guanosine triphosphate (GTP) hydrolytic activity.

If the outside temperature decreases by 20 degrees Celsius, what will happen to a reptile’s body temperature?
oksian1 [2.3K]

The reptile's body temperature rises when the external temperature rises. When the temperature drops, so does his body temperature. If a reptile feels cold because the external temperatures have made his blood cold, he'll lie in the sun to warm up. However, if the external temperature is too high, he scurries under a rock, dives in a pool or finds some kind of shade where he can cool down. Reptiles and other animals with ectothermic systems are vulnerable to extreme changes in temperature because they can't control their temperatures internally. They can control their body temperatures only by moving to an environment with a suitable ambient temperature.
