FunctionComponent of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Involved in the histone 3' end pre-mRNA processing.
Sequence similaritiesBelongs to the metallo-beta-lactamase superfamily. RNA-metabolizing metallo-beta-lactamase-like family. CPSF2/YSH1 subfamily.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human pancreatic islet cell tumor (left) and mouse teratoma (right) tissues labelling CPSF2/CPSF100 with ab81553 at 1/200 (1µg/ml). Detection: DAB.
All lanes : Anti-CPSF2/CPSF100 antibody (ab81553) at 0.04 µg/ml
Lane 1 : HeLa whole cell lysate at 50 µg
Lane 2 : HeLa whole cell lysate at 15 µg
Lane 3 : HeLa whole cell lysate at 5 µg
Lane 4 : 293T whole cell lysate at 50 µg

Predicted band size: 88 kDa
Observed band size: 100 kDa why is the actual band size different from the predicted?
Additional bands at: 80 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 30 seconds
HeLa cell lysate (1mg) was immunoprecipitated using ab81553 at 3µg/mg (lane 1) or IgG control (lane 2). 20% of the immunoprecipitate was analysed by Western blotting using ab81553 at 1µg/ml. Bands were observed by chemiluminescence with a 3 second exposure time.
