keratinization
|
GO_0031424 |
[The process in which the cytoplasm of the outermost cells of the vertebrate epidermis is replaced by keratin. Keratinization occurs in the stratum corneum, feathers, hair, claws, nails, hooves, and horns.] |
|
polycistronic mRNA processing
|
GO_0031426 |
[The conversion of a primary mRNA transcript containing more than one complete protein-coding region into individual mature mRNA molecules.] |
|
response to methotrexate
|
GO_0031427 |
[Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a methotrexate stimulus. Methotrexate is 4-amino-10-methylformic acid, a folic acid analogue that is a potent competitive inhibitor of dihydrofolate reductase.] |
|
box C/D methylation guide snoRNP complex
|
GO_0031428 |
[A ribonucleoprotein complex containing a box C/D type RNA that is capable of ribose-2'-O-methylation of target RNAs. Box C/D type RNAs are widespread in eukaryotes and in Archaea, suggesting that an RNA-based guide mechanism for directing specific RNA 2'-O-ribose methylations was present in the common ancestor of Archaea and Eukarya.] |
|
box C/D RNP complex
|
GO_0170049 |
[A ribonucleoprotein complex consisting of a box C/D type snRNA and three (Archaea) or four (Eukaryotes) core proteins that have diverse functions, including site-specific methylation of rRNA and processing rRNA.] |
|
box H/ACA snoRNP complex
|
GO_0031429 |
[A box H/ACA small nucleolar ribonucleoprotein complex located in the nucleolus that catalyzes pseudouridylation of ribosomal RNA residues. The complex is composed of four different core proteins that assemble onto a H/ACA guide RNA scaffold that identifies specific uridines in rRNA for modification during ribosome synthesis.] |
|
box H/ACA RNP complex
|
GO_0072588 |
[A ribonucleoprotein complex that contains an RNA of the box H/ACA type and the four core proteins dyskerin, NOP10, NHP2, and GAR1 (human protein nomenclature). RNA pseudouridylation (isomerization of uridine to pseudouridine) is the major, and most likely the ancestral, function of H/ACA RNPs. Pseudouridylation targets include both large and small ribosomal RNAs (rRNAs), and small nuclear RNA (U2 snRNA). In addition to these catalytic H/ACA RNPs, a less abundant but more diverse class of structural H/ACA RNPs exists, which does not have pseudouridylation activity. These include the vertebrate telomerase RNP complex.] |
|
protein dephosphorylation
|
GO_0006470 |
[The process of removing one or more phosphoric residues from a protein.] |
|
dephosphorylation
|
GO_0016311 |
[The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.] |
|
obsolete protein ADP-ribosylation
|
GO_0006471 |
[OBSOLETE. The transfer, from NAD, of ADP-ribose to protein amino acids.] |
|
GO_0006472
|
GO_0006472 |
|
|
N-terminal protein amino acid acetylation
|
GO_0006474 |
[The acetylation of the N-terminal amino acid of proteins.] |
|
N-terminal protein amino acid modification

GO_0031365 |
[The alteration of the N-terminal amino acid residue in a protein.] |
|
internal protein amino acid acetylation
|
GO_0006475 |
[The addition of an acetyl group to a non-terminal amino acid in a protein.] |
|
protein sulfation
|
GO_0006477 |
[The addition of a sulfate group as an ester to a protein amino acid.] |
|
sulfation
|
GO_0051923 |
[The addition of a sulfate group to a molecule.] |
|
gas vesicle
|
GO_0031411 |
[An intracellular non-membrane-bounded organelle; a hollow structure made of protein, which usually has the form of a cylindrical tube closed by conical end caps. By regulating their relative gas vesicle content, aquatic microbes are able to perform vertical migrations.] |
|
peptidyl-tyrosine sulfation
|
GO_0006478 |
[The sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.] |
