GuDViN [60]3 years ago

<span>Astigmatism refers to an irregular curvature of the cornea, the front surface of the eye. This curvature affects the ability of the eye to focus, and can result in distortion or blurring of vision, both near and far, as well as headaches, squinting and eye discomfort. Astigmatism is very common and can be corrected by wearing glasses or contact lenses. Laser eye surgery can also reshape the cornea, but is usually performed only in adults, since vision may continue to change throughout adolescence.</span>

Many receptor tyrosine kinase pathways have mapk as a downstream signaling component. mapk can phosphorylate target proteins. wh
Lapatulllka [165]

A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).

<h3>Mitogen-activated protein kinase :</h3>

A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.

In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.

Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.

The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.

Does anyone know the answer to this ? What happens if you poke a hole in the plastic bottle of a balloon lung model?
o-na [289]
Then the model will become useless. originally the bottle should be air tight only tubes connected to the balloons, so that pressure can be shown when you adjust the plastic sheet in the bottom of the model. but now if there's a hole, air can move freely in or out the bottle and the model will not be able to show anything that occurs during respiration
