CC -!- FUNCTION: Component of the cleavage and polyadenylation specificity
CC factor (CPSF) complex that plays a key role in pre-mRNA 3'-end
CC formation, recognizing the AAUAAA signal sequence and interacting with
CC poly(A) polymerase and other factors to bring about cleavage and
CC poly(A) addition. Has endonuclease activity. Binds RNA polymers with a
CC preference for G- and/or C-rich clusters. Binds single-stranded DNA
CC non-specifically. {ECO:0000269|PubMed:8943320,
CC ECO:0000269|PubMed:9512528}.
CC -!- SUBUNIT: Component of the cleavage and polyadenylation specificity
CC factor (CPSF) complex, composed of at least Clp, Cpsf73, Cpsf100 and
CC Cpsf160. {ECO:0000269|PubMed:19450530}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:9512528}.
CC -!- TISSUE SPECIFICITY: During oogenesis, expression is detected in the
CC germarium, in nurse cells, in the oocyte, and in the somatically
CC derived follicular epithelial cells (at protein level). At oogenesis
CC stage 12, nurse cells degenerate and their content is transferred into
CC the oocyte. In larvae, expressed in all organs and disks (at protein
CC level). In the larval salivary gland, expression is initially confined
CC to cells at the anterior end but later expands throughout the entire
CC gland (at protein level). {ECO:0000269|PubMed:8943320,
CC ECO:0000269|PubMed:9512528}.
CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically. During
CC embryogenesis expressed only at transcript level. Expressed in larvae
CC (at protein level), pupae and adults. Initial embryonic expression is
CC maternally derived, then gradually decreases until third-instar larvae
CC when there is a burst of zygotic expression. Most of the female
CC expression is ovarian (at protein level). {ECO:0000269|PubMed:8943320,
CC ECO:0000269|PubMed:9512528}.
CC -!- DOMAIN: The N-terminal region containing the five C3H1-type zinc
CC fingers is essential for endonuclease activity.
CC {ECO:0000269|PubMed:8943320}.
CC -!- DOMAIN: The C-terminal region containing the two CCHC-type zinc fingers
CC confers a binding preference for RNAs that contain G- and/or C-rich
CC clusters. {ECO:0000269|PubMed:9512528}.
