GTPase-activating proteins or GTPase-accelerating proteins (GAPs) are a family of regulatory proteins whose members can bind to activated G proteins and stimulate their GTPase activity, with the result of terminating the signaling event. [1] GAPs are also known as RGS protein, or RGS proteins, [2] and these proteins are crucial in controlling ...
Anatomical terminology. [ edit on Wikidata] Gap junctions are membrane channels between adjacent cells that allow the direct exchange of cytoplasmic substances. [ 1 ] Substances exchanged include small molecules, substrates, and metabolites. [ 1 ] Gap junctions were first described as close appositions as other tight junctions, but following ...
A gap gene is a type of gene involved in the development of the segmented embryos of some arthropods. Gap genes are defined by the effect of a mutation in that gene, which causes the loss of contiguous body segments, resembling a gap in the normal body plan. Each gap gene, therefore, is necessary for the development of a section of the organism ...
Sequence alignment. In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. [1] Aligned sequences of nucleotide or amino acid residues are typically represented ...
Bioinformatics uses biology, chemistry, physics, computer science, computer programming, information engineering, mathematics and statistics to analyze and interpret biological data. The subsequent process of analyzing and interpreting data is often referred to as computational biology, though the distinction between the two terms is often ...
incisura myelini. MeSH. D011901. TH. H2.00.06.2.03015. Anatomical terms of microanatomy. [edit on Wikidata] In neuroscience and anatomy, nodes of Ranvier (/ ˈrɑːnvieɪ / RAHN-vee-ay), [1][2] also known as myelin-sheath gaps, occur along a myelinated axon where the axolemma is exposed to the extracellular space.
The Gap Analysis Project mission is to provide state, regional, and national biodiversity assessments of the conservation status of native vertebrate species, aquatic species, and natural land cover types and to facilitate the application of this information to land management activities. The stated goal of GAP is “keeping common species ...
Gap analysis involves determining, documenting and improving the difference between business requirements and current capabilities. Gap analysis naturally flows from benchmarking and from other assessments. Once the general expectation of performance in an industry is understood, it is possible to compare that expectation with the company's ...
