centrosomal protein of 57 kD; Cep57; FGF2-interacting protein; testis-specific protein 57; translokin (CEP57, KIAA0092, TSP57)
Function:
- centrosomal protein
- may be required for microtubule attachment to centrosomes
- may act by forming ring-like structures around microtubules
- mediates nuclear translocation & mitogenic activity of the internalized growth factor FGF2 (putative)
- interacts with microtubules
- interacts with FGF2 & RAP80
- does not interact with FGF1 or FGF2 isoform 24 kD
Structure:
- homodimer & homooligomer
- the C-terminal region mediates interaction with microtubules & is able to nucleate & bundles microtubules in vitro (putative)
- the centrosome localization domain (CLD) region mediates the localization to centrosomes & homooligomerization
- belongs to the translokin family
Compartment:
- nucleus (putative)
- cytoplasm, cytoskeleton, centrosome
Alternative splicing: named isoforms=4
Expression: ubiquitous
Pathology:
- defects in CEP57 are the cause of mosaic variegated aneuploidy syndrome type 2
