Motility also includes physiological processes like gastrointestinal movements and peristalsis. Understanding motility is important in biology, medicine, and ecology, as it impacts processes ranging from bacterial behavior to ecosystem dynamics.
ITIM motifs are defined as six amino acid signature with the consensus sequence S/I/V/LxYxxL/V, where x stands for any amino acid, Y for a tyrosine residue that can be phosphorylated and S, I, V for amino acids serine, isoleucine, and valine, respectively. [2]
A ribosome is a biological machine that utilizes protein dynamics. Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms.
Generally sessile Hydra attached to a substrate. Sessility is the biological property of an animal describing its lack of a means of self-locomotion. Sessile animals for which natural motility is absent are normally immobile.
In a chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a common three-dimensional structure that appears in a variety of different, evolutionarily unrelated molecules. [1]
PAM and size of various CRISPR DNA nucleases . The canonical PAM is the sequence 5'-NGG-3', where "N" is any nucleobase followed by two guanine ("G") nucleobases. [9] Guide RNAs can transport Cas9 to any locus in the genome for gene editing, but no editing can occur at any site other than one at which Cas9 recognizes PAM.
In biology, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and usually assumed to be related to biological function of the macromolecule. For example, an N -glycosylation site motif can be defined as Asn, followed by anything but Pro, followed by either Ser or Thr, followed by anything but Pro residue .
Motilin is a 22-amino acid polypeptide hormone in the motilin family that, in humans, is encoded by the MLN gene. [2]Motilin is secreted by endocrine Mo cells [3] [4] (also referred to as M cells, which are not the same as the M cells, or microfold cells, found in Peyer's patches) that are numerous in crypts of the small intestine, especially in the duodenum and jejunum.
