Protein attributes

Sequence length	229 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Required for recruitment of CENPA to centromeres and normal chromosome segregation during mitosis. Ref.3
Subunit structure	Homodimer, and heterodimer with MIS18A. Identified in a complex containing MIS18A, MIS18B, MIS18BP1, RBBP7 and RBBP4. Binds outer membrane protein OpaP from Neisseria gonorrhoeae.
Subcellular location	Nucleus. Chromosome. Chromosome › centromere. Note: Associated with centromeres in interphase cells, from late anaphase to the G1 phase. Not detected on centromeres during earlier phases of mitosis. Associated with chromatin. Ref.3
Sequence caution	The sequence AAC39561.1 differs from that shown. Reason: Erroneous initiation.
