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.

What causes the myosin head to move into the 'cocked' position after it is released from actin? Group of answer choices ATP bind
kupik [55]

Answer:

Explanation:

The molecular and cellular mechanisms and processes that explain muscle contraction in striated muscle occur in the myofibril sarcomere. Their understanding depends on the organization's understanding of the structure of the sarcomere. In an imaginary experiment we first assemble an ideal sarcomere.

Remember that the myofibril is a set of cylindrical compartments that are located next to each other, constituting an elongated cylinder. Each of these cylinders is a sarcomere and borders its neighbor on a line or band called, line or band z.

On each side of the z line, thin cylindrical filaments that are actin filaments are inserted. Each actin filament is formed by a double strand of actin molecules that are rolled over each other. In this organization, actin is called actin F.
