- IgA immunoglobulin complex
A protein complex composed of two identical immunoglobulin heavy chains of the IgA isotype and two identical immunoglobulin light chains, held together by disulfide bonds, and sometimes complexed with J chain or J chain and secretory component. An IgA immunoglobulin complex may be embedded in the plasma membrane or present in the extracellular space, in mucosal areas or other tissues, or circulating in the blood or lymph.
- V(D)J recombination
The process in which immune receptor V, D, and J, or V and J gene segments, depending on the specific receptor, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- T cell receptor V(D)J recombination
The process in which T cell receptor V, D, and J, or V and J gene segments, depending on the specific locus, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- hyphal growth
Growth of fungi as threadlike, tubular structures that may contain multiple nuclei and may or may not be divided internally by septa, or cross-walls.
- CTPase activity
Catalysis of the reaction: CTP + H2O = CDP + H+ + phosphate. May or may not be coupled to another reaction.
- somatic diversification of immune receptors by N region addition
The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of heavy chain immunoglobulin and T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the immune receptor gene.
