The extrinsic pathway of apoptosis activated through Fas death receptors. Trimeric Fas ligands on the surface of a killer lymphocyte interact with trimeric Fas receptors on the surface of the target cell, leading to clustering of several ligand-bound receptor trimers (only one trimer is shown here for clarity). Receptor clustering activates death domains on the receptor tails, which interact wi...

#cellbiology #apoptosis #cancer Caspase activation during apoptosis. An initiator caspase contains a protease domain in its carboxy-terminal region and a small protein interaction domain near its amino terminus. It is initially made in an inactive, monomeric form, sometimes called procaspase. Apoptotic signals trigger the assembly of adaptor proteins carrying multiple binding sites for the casp...

#cellsignaling #mitogen #cellcycle Mitogens are signaling molecules that bind to cell-surface receptors and initiate a cascade of intracellular signaling pathways that are essential for cell growth and division. One of the key pathways activated by mitogens involves the small GTPase Ras. Upon activation, Ras engages the MAP kinase (MAPK) cascade, a series of protein kinases that transmit the gr...

Auxin Signaling Mechanism: In the Absence of Auxin: Aux/IAA Proteins: These are transcriptional repressor proteins that, in the absence of auxin, bind to and inhibit auxin-response factors (ARFs). ARFs: ARFs are transcription regulatory proteins essential for the transcription of auxin-responsive genes. However, without auxin, they are suppressed by Aux/IAA proteins, preventing the expression o...

When DNA is damaged, various protein kinases are recruited to the site of damage and initiate a signaling pathway that causes cell-cycle arrest. The first kinase at the damage site is either ATM or ATR, depending on the type of damage. Additional protein kinases, called Chk1 and Chk2, are then recruited and activated, resulting in the phosphorylation of the transcription regulatory protein p53....
