- *********************************
- * 'Paired box' domain signature *
- *********************************
-
- The 'paired box' [1,2] is a 124 amino-acid conserved domain which has been
- found in the proteins listed below (references are only provided for recently
- determined sequences).
-
- - Drosophila segmentation pair-rule class protein paired (prd).
- - Drosophila segmentation polarity class proteins gooseberry proximal (gsb-p),
- and gooseberry distal (gsb-d).
- - Drosophila proteins Pox-meso and Pox-neuro [3].
- - Mammalian protein Pax1, which may play a role in the formation of segmented
- structures in the embryo.
- - Mammalian protein Pax3 [5]. Pax3 is expressed during early neurogenesis.
- In Man, defects in Pax3 are the cause of Waardenburg's syndrome (WS), an
- autosomal dominant combination of deafness and pigmentary disturbance.
- - Mammalian protein Pax6 (oculorhombin) [6]. Pax6 is probably a transcription
- factor with important functions in eye and nasal development. In Man,
- defects in Pax6 are the cause of aniridia type II (AN2), an autosomal
- dominant disorder characterized by complete or partial absence of the iris.
- - Mammalian protein Pax7.
- - Mammalian protein Pax8.
- - Zebrafish protein Pax[Zf-a] [7].
-
- The function of this conserved domain is not yet known. This domain is
- generally located in the N-terminal section of the proteins. In some of these
- proteins, there is a homeobox domain upstream of the paired box.
-
- We use the region spanning positions 35 to 51 of the paired box, as a
- signature pattern.
-
- -Consensus pattern: R-P-C-x(11)-C-V-S
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
