Descriptions

lab is a member of the Homeotic complex (HOX) family of homeoproteins that are required for specifying cell fates and morphological differences along the anterior-posterior axes of most animals. The lab hexapeptide(also called YPWM motif or pentapeptide) inhibits lab function and activates inappropriate target genes in vivo by inhibiting DNA binding. LAB-EXD interactions functions to remove the inhibitory effect of the hexapeptide and to enhance DNA binding to relevant target sequences by cooperative interactions.

1 GO annotations of cellular component

Name Definition
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

2 GO annotations of molecular function

Name Definition
DNA-binding transcription factor activity, RNA polymerase II-specific A DNA-binding transcription factor activity that modulates the transcription of specific gene sets transcribed by RNA polymerase II.
RNA polymerase II cis-regulatory region sequence-specific DNA binding Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by RNA polymerase II.

1 GO annotations of biological process

Name Definition
regulation of transcription by RNA polymerase II Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II.
