Membrane proteins are not soluble in water solutions. To purify and crystallize membrane proteins, the proteins need to be disso
katrin2010 [14]

Answer:

Detergents are knows as a class of molecules whose having unique properties to enable formation of hydrophobic-hydrophilic interaction among molecules in membrane. This unique property of detergents are used to dissolve membrane protein in water solution or in any solution.

Detergents are used to lyse cells, solubilize membrane lipids, and proteins, prevent protein crystalization, and nonspecific binding.

1.) You are studying P120, a protein of 120 KDa that is continuously synthesized in eukaryotic cells. Its cellular concentration
irina1246 [14]

Answer:

1. P120 is degraded in the 26S proteasome

2. The 26S proteasome has a major role in protein degradation and is critical for protein homeostasis

3. Cell cycle and DNA replication are cellular processes regulated by the Ras and NFkB pathways

Explanation:

The proliferation-associated nucleolar protein (p120) is a protein known to be expressed during the interphase of the cell cycle, specifically in G1 and early S phase, where any problem with DNA replication trigger a checkpoint, i.e., a molecular cascade of signaling events that suspend DNA replication until the problem is resolved. In mammalian cells, the 26S proteasome is responsible for catalyzing protein degradation of about 80% (or even more) of their proteins. The 26S proteasome acts to degrade rapidly misfolded and regulatory proteins involved in the cell cycle, thereby having a major role in protein homeostasis and in the control of cellular processes. It is for that reason that inhibitors that block 26S proteasome function have shown to be useful as therapeutic agents in diseases associated with the failure of protein degradation mechanisms (e.g., multiple myeloma). The NF-κB are highly conserved transcription factors capable of regulating different cellular processes including, among others, cellular growth, inflammatory responses and apoptosis. Moreover, the MAPK/ERK pathway is able to transduce different signals received on the cell surface to the nucleus. The MAPK/ERK pathway is activated when a singling molecule binds to a cell receptor which triggers a signaling cascade that ends when a transcription factor induces the expression of target genes, ultimately producing a response in the cell (for example, the progression through the cell cycle).

According to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts?
tatyana61 [14]

Answer:

This process would be the one truly responsible for the "evolution" of mitochondria and chloroplasts as we know them from their prokaryotic ancestors. The cell process that would have initiated endosymbiosis is endocytosis; the process of taking things inside the cell
