Protein attributes

Sequence length	404 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in centrosome duplication and mitotic progression By similarity.
Subunit structure	May be part of a SHFM1-containing complex. Ref.4
Subcellular location	Cytoplasm › cytoskeleton › centrosome By similarity. Cytoplasm › cytoskeleton › spindle By similarity. Note: Localizes on centrosomes in interphase cells and at spindles in mitosis By similarity.
Sequence similarities	Belongs to the SAC3 family.
Caution	It is uncertain whether Met-1 or Met-47 is the initiator.
Sequence caution	The sequence AP003068 differs from that shown. Reason: Erroneous gene model prediction.
