Summary Information
Automatically generated summary See sections below for more information	The gene prickle is referred to in FlyBase by the symbol pk (CG11084, FBgn0003090). It has the cytological map location 42F3-43A1. Its sequence location is 2R:3038207..3110885. Its molecular function is described as: protein binding; zinc ion binding. It is involved in the biological processes: establishment of ommatidial polarity; establishment and/or maintenance of cell polarity; establishment of planar polarity; protein localization; establishment of protein localization; maintenance of protein localization; establishment of imaginal disc-derived wing hair orientation. 90 alleles are reported. The phenotypes of these alleles are annotated with 18 unique terms, many of which group under: adult segment; peripheral nervous system; thoracic segment; nervous system; appendage segment; adult mesothoracic segment; organ system; metatarsus; wing hair; adult. It has 3 annotated transcripts and 3 annotated polypeptides.

Phenotypic Description from the Red Book (Lindsley & Zimm 1992)
Gene/Allele symbols may differ from current usage	pk: prickle Polarity pattern of wing, haltere, and notum altered in mutants. Chaetae of triple row on anterior wing slanted anteriorly instead of posteriorly. Trichomes near L2 vein arranged in counterclockwise whorl on right wing blade, in clockwise whorl on left blade; trichomes in anterior wing occasionally duplicated (Gubb and Garcia-Bellido, 1982). On the notum, the posterior acrostichals are irregularly erect and whorled. Occasionally, extra dorsocentral and scutellar bristles appear at temperatures above 23. Mutant flies slightly larger than wild type. Gubb and Garcia-Bellido (1982) describe somatic clones of homozygous pk cells. sple: spiny legs Polarity of chaetae and trichomes on legs irregular; relations between bracts and bristles disrupted. High incidence of ectopic tarsal joints with inverted polarity, especially in tarsae 3 and 4; incomplete intersegmental membranes between tarsal segments, especially between segments 3 and 4; no extra sensilla companiformia despite extra joints. Chaetae on abdominal tergites turned toward midline instead of pointing posteriorly as in wild type; polarity of bristles on sternites disrupted as well. sple3 A low-temperature-sensitive allele. Legs of flies raised at 19 highly condensed with incomplete joints, haphazard bristle pattern, occasional increase in number of bristle rows, and absence of some prominent markers. Flies unable to walk and soon get stuck in food. In sple3 flies raised at 28 53% of legs, though apparently normal, display abnormalities such as swollen second, third, and fourth tarsal segments, abnormal tarsal joints and reversals in bristle orientation in the middle of every segment; such flies able to walk and breed. About 30% of legs show phenotype intermediate between the two phenotypes described above. Mutant phenotype expressed in the homeotic legs of Antp and ssa; also expressed in mitotic clones.
