RN [1] {ECO:0000312|EMBL:AAH76956.1}
RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC TISSUE=Embryo {ECO:0000312|EMBL:AAH76956.1};
RG NIH - Xenopus Gene Collection (XGC) project;
RL Submitted (JUL-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Binds and protects the poly(A) tail of mRNA with or without
CC an AU-rich element (ARE) and prevents mRNA deadenylation. Stimulates
CC the translation of mRNAs to which it is bound during early development
CC (By similarity). {ECO:0000250|UniProtKB:Q98SP8}.
CC -!- SUBUNIT: Interacts with dazl in an RNA-independent manner. The C-
CC terminus can self-associate and also interact with the C-terminus of
CC pabpc1, independently of RNA. RRM 1 and RRM 2 interact with both eif4g1
CC and paip1, and the C-terminus also interacts with paip1. Prior to
CC oocyte maturation, found in a complex with dazl and pum2 proteins and
CC spdy1 mRNA; pum2 dissociates from the complex during maturation.
CC Interacts with the translation termination factor sup35/erf3 (By
CC similarity). {ECO:0000250|UniProtKB:Q98SP8}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Note=Associated with
CC polysomes. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the polyadenylate-binding protein type-1 family.
CC {ECO:0000305}.
