The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/2000 - 1/10000. Detects a band of approximately 45 kDa (predicted molecular weight: 45 kDa).
Use at 2-5 µg/mg of lysate.
Guanine-nucleotide releasing factor that promotes the exchange of Ran-bound GDP by GTP. Involved in the regulation of onset of chromosome condensation in the S phase. Binds both to the nucleosomes and double-stranded DNA. RCC1-Ran complex (together with other proteins) acts as a component of a signal transmission pathway that detects unreplicated DNA. Plays a key role in nucleo-cytoplasmic transport, mitosis and nuclear-envelope assembly.
Contains 7 RCC1 repeats.
N-terminal methylation by METTL11A/NTM1 is required for binding double-stranded DNA and stable chromatin association. Di-and trimethylation produce a permanent positive charge on the amino group, which facilitate electrostatic binding to the phosphate groups on DNA, while inhibiting histone-binding. Methylated tail helps retain RCC1 on chromosomes during nucleotide exchange on Ran.
Nucleus. Cytoplasm. Becomes dispersed throughout the cytoplasm during mitosis.
