Description

Distal deletion breakpoint maps between Pm and Pe, such that Pm is eliminated but Pe is intact.

(Bernstein and Cline, 1994)

Deletion of the promoter for male and female late transcripts, the early promoter is intact and functional.

(Bell et al., 1991)

Deletion of sequences extending proximally away from Sxl.

      SxlfPRJ2/Sxlf1 shows wild type dosage compensation in run25 phenotype assay.

      (Bernstein and Cline, 1994)

      Partial loss of function allele. Does not complement Sxlf1. Partially complements Sxl alleles that are defective in somatic function, suggesting that this allele retains some somatic function. Partially complements Sxlf2, an allele defective in germline function; heteroallelic females are semi-fertile and the ovaries do not contain any abnormal oocytes.

      Comments

      The failure of SxlfPRJ2 to complement Sxlf1 shows that sequences proximal to coordinate 0 (coordinates according to FBrf0042036) are required for wild-type Sxl activity.

      (Salz et al., 1987)

      Defective in Sxl Pm-mediated activities - the later functions governing maintenance and expression of the female-committed developmental state. Complements Sxlf9, and partially complements Sxlf2 for female viability. Shows dominant masculinizing interactions with snf that are as strong as for a Sxl deficiency.
