CC -!- FUNCTION: May play a role in myoblast differentiation. When CC unphosphorylated, associates with an ELAVL1-containing complex, which CC stabilizes cyclin mRNA and ensuring cell proliferation. Phosphorylation CC by AKT2 impairs this association, leading to CCND1 mRNA destabilization CC and progression towards differentiation. {ECO:0000269|PubMed:20019746}. CC -!- FUNCTION: [Isoform Ptx2c]: Involved in the establishment of left-right CC asymmetry in the developing embryo. {ECO:0000269|PubMed:10585561}. CC -!- SUBUNIT: Interacts with EFEMP2 (By similarity). Interacts (when CC unphosphorylated on Thr-90) with ELAVL1/HUR (PubMed:20019746).

CC {ECO:0000269|PubMed:11319841, ECO:0000269|PubMed:9147650}. CC -!- DEVELOPMENTAL STAGE: Detected as early as 8.5 dpc (PubMed:9147650). At CC 9.5 dpc, detected in ectodermal cells in first branchial arch, CC ventrolateral dermomyotome of early somites and neural tissues CC (PubMed:9539779). In the developing brain, at 9.5-11.5 dpc, expressed CC in the ventral diencephalon and zona limitans intrathalamica (ZLI), as CC well as in the lateral plate mesenchyme, mandibular and maxillary CC epithelium and the vitelline and umbilical vessels (PubMed:8944018, CC PubMed:9347917). At 11.5 dpc, also detected in the mesenchyme around CC the eye, Rathke's pouch, the dental lamina, the limb mesenchyme and the CC dorsal mesentery (PubMed:8944018). At 12.5 dpc, detected in the ZLI and CC in the mammillary area, as well as in Rathke's pouch. At 14.5 dpc, CC expressed in early ventral lateral geniculate nucleus. At 18.5 dpc, CC expressed along the anterioposterior axis in the ventral lateral CC geniculate nucleus (PubMed:9347917). {ECO:0000269|PubMed:8944018, CC ECO:0000269|PubMed:9147650, ECO:0000269|PubMed:9347917, CC ECO:0000269|PubMed:9539779}. CC -!- DEVELOPMENTAL STAGE: [Isoform Ptx2c]: At 8.5 dpc, expressed CC asymmetrically in the left lateral plate mesoderm and symmetrically in CC the head mesoderm (PubMed:10585561, PubMed:15475956). At 13.5 dpc, CC expressed in the heart, in the left atrium and right ventricle. At this CC stage, also expressed in the gastro-intestinal tract, in the left side CC of the stomach, the cecum, the small intestine and the superior CC mesenteric artery (PubMed:10585561). In the developing heart, at 15.5 CC dpc, expressed in the ventral aspects of the outflow tract region and CC of the right ventricle and also in the left atrium (PubMed:15475956). CC {ECO:0000269|PubMed:10585561, ECO:0000269|PubMed:15475956}. CC -!- INDUCTION: Expression is activated by CITED2 and TFAP2A and TFAP2C. CC {ECO:0000269|PubMed:15475956}. CC -!- PTM: Phosphorylated at Thr-90 by AKT2, but not AKT1. Phosphorylation CC impairs its association with a CCND1 mRNA-stabilizing complex, thus CC shortening the half-life of CCND1. {ECO:0000269|PubMed:20019746}. CC -!- DISRUPTION PHENOTYPE: [Isoform Ptx2c]: Knockout embryos exhibit cardiac CC and laterality defects. Embryos have defects in the aortic arch CC vessels, such as double-outlet right ventricle and right-sided or CC double aortic arches. Most have bilateral, left-sided or midline CC inferior caval veins, right atrial and pulmonary isomerism. None have CC abnormal ventricular topology, but some have malposition of the heart CC to the right and the hearts of the remaining embryos are in the midline CC rather than to the left. In addition, most embryos have ventricular CC septal defects with associated double-outlet right ventricle. Some CC embryos show right-sided aortic arches and some have right-sided CC stomachs or, in one case, a midline stomach. The spleen is absent or CC small. Unlike mice lacking all Pitx2 isoforms, Pitx2c-specific knockout CC embryos have no defects in ventral body wall closure. CC {ECO:0000269|PubMed:15475956}. CC -!- MISCELLANEOUS: [Isoform Pitx2Cbeta]: Produced by alternative initiation CC at Met-35 of isoform Ptx2C. {ECO:0000305}. CC -!- SIMILARITY: Belongs to the paired homeobox family. Bicoid subfamily. CC {ECO:0000305}.
