Zinc finger protein ZIC 3

Gene

zic3

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Probably acts as a transcriptional activator. May bind to the minimal GLI-consensus sequence 5'-GGGTGGTC-3'. Can determine the ectodermal cell fate and promote the earliest step of neural and neural crest development. Involved in establishing left-right asymmetry in the embryo.3 Publications

Expressioni

Tissue specificityi

First detected at early gastrula (stage 10.25) in the dorsal lip and prospective neural plate. Also expressed in the mesoderm at early gastrulation, with expression strongest on the dorsal side. Mesodermal expression continues at stage 12 but is hardly detectable after stage 14. As gastrulation proceeds, expression decreases in the dorsal lip and increases in the prospective neural plate. At the neural plate stage (stage 14), expressed strongly in the prospective mesencephalon and anterior rhombencephalon, after which expression becomes stronger in the anterior neural folds. At early tailbud stage (stage 20), expression becomes restricted to the dorsal region of forebrain, midbrain and hindbrain, and weakly to the dorsal trunk. After mid-tailbud stage, expression decreases in the diencephalon, appears in the lateral mesoderm of the tailbud region and becomes restricted in the dorsal part of the neural tube.3 Publications

Developmental stagei

Expressed zygotically. First expressed from the late blastula.3 Publications

Inductioni

By dvr1/vg1, activin and t/bra in the mesoderm. By heteromeric AP-1 (fos/jun) during activin signaling. By increases in Ca2+ in the dorsal ectoderm, triggered by planar signals from the mesoderm. Suppressed by bmp-signaling. By pbx1 and meis1. By zic1, zic2 and zic3 but not zic5.7 Publications

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
