a WD40 repeat protein. Component of the methylosome, a 20S complex containing at least ICLN, SKB1 and WDR77. Interacts with SKB1 and with SM proteins. The methylosome may regulate an early step in the assembly of U snRNPs, possibly the transfer of Sm proteins to the SMN-complex. WD40 repeats are found in a number of eukaryotic proteins that coordinate multi-protein complex assemblies. WD40 proteins are implicated in many functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing and cytoskeleton assembly. Note: This description may include information from UniProtKB.
Protein type: Nuclear receptor co-regulator; Adaptor/scaffold; Transcription, coactivator/corepressor
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
