nickel cation binding

Binding to a nickel (Ni) cation.

nickel cation transmembrane transporter activity

Enables the transfer of nickel (Ni) cations from one side of a membrane to the other.

nickel cation transmembrane transport

The directed movement of nickel (Ni) cations across a membrane by means of some agent such as a transporter or pore.

nickel cation transport

The directed movement of nickel (Ni) cations into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

4 iron, 3 sulfur cluster binding

Binding to a 4 iron, 3 sulfur (4Fe-3S) cluster, an uncommon iron-sulfur cluster with unique properties found in oxygen-tolerant Ni-Fe hydrogenases of various bacteria.

high-affinity nickel cation transmembrane transporter activity

Catalysis of the high-affinity transfer of nickel (Ni) cations from one side of a membrane to the other. In high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations.

polymeric immunoglobulin binding

Binding to a J-chain-containing polymeric immunoglobulin of the IgA or IgM isotypes.

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).

somatic diversification of T cell receptor genes by N region addition

The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the T cell receptor gene.
