pyrimidine dimer repair

The repair of UV-induced T-T, C-T and C-C dimers.

photoreactive repair

The repair of UV-induced T-T, C-T and C-C dimers by directly reversing the damage to restore the original pyrimidines.

pyrimidine dimer repair by nucleotide-excision repair

The repair of UV-induced T-T, C-T, and C-C dimers by the recognition and removal of the damaged DNA strand from the DNA helix as an oligonucleotide. The small gap left in the DNA helix is filled in by the sequential action of DNA polymerase and DNA ligase.

cytosine/thymine mispair binding

Binding to a double-stranded DNA region containing a C/T mispair.

thymine/thymine mispair binding

Binding to a double-stranded DNA region containing a T/T mispair.

aclacinomycin T methylesterase activity

Catalysis of the reaction: aclacinomycin T(1+) + H2O = 15-demethylaclacinomycin T + methanol + H+.

CD4-positive or CD8-positive, alpha-beta T cell lineage commitment

The process in which an immature T cell commits to CD4-positive T cell lineage or the CD8-positive lineage of alpha-beta T cells.

alpha-beta T cell differentiation

The process in which a precursor cell type acquires the specialized features of an alpha-beta T cell. An alpha-beta T cell is a T cell that expresses an alpha-beta T cell receptor complex.

gamma-delta T cell differentiation

The process in which a relatively unspecialized hemopoietic cell acquires specialized features of a gamma-delta T cell. A gamma-delta T cell is a T cell that expresses a gamma-delta T cell receptor complex.

T cell proliferation

The expansion of a T cell population by cell division. Follows T cell activation.
