Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp m
kodGreya [7K]

Answer:

A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.

Explanation:

Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.

Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.

Which of the following is the downstream signaling protein for the TRADD-associated complex in the cell survival path of TNF sig
grigory [225]

Answer:

The correct answer is - option A. IKK.

Explanation:

In signal transduction or any other molecular biology process, the upstream or downstream is related to the molecular or cellular events that follow a mechanistic and temporal order.

In TNF signaling involved in cell survival pathway the TRADD- associated complex also is known as TNF receptor-associated death domain complex has a second messenger that activates temporally after the cell membrane receptor known as IKK signaling protein that help in numerous downstream pathways.

Thus, the correct answer is - option A. IKK.
