Rodent Malaria ParasiteP. berghei
Parent strain/lineP. berghei ANKA
Name parent line/clone RMgm-1314
Other information parent lineThis line expresses the PfLSA1 (accession no. PF3D7_1036400) coding sequence (CDS) under the control of the Pbuis4 regulatory sequences and a fusion protein of GFP and firefly luciferase (LUC-IAV) under the control of the constitutive Pbeef1a promoter. Both the PfLSA1 and Luc-gfp expression cassettes are integrated into the neutral 230p locus in chromosome 3.

Additional remarks phenotype

Mutant/mutation
This GIMO mutant contains a hdfr/yfcu selection marker (SM) cassette in the neutral s1 (PBANKA_1206800) gene locus. The SM cassette has been introduced in the s1 locus of line RMgm-1314. This line expresses the PfLSA1 (accession no. PF3D7_1036400) coding sequence (CDS) under the control of the Pbuis4 regulatory sequences and a fusion protein of GFP and firefly luciferase (LUC-IAV) under the control of the constitutive Pbeef1α promoter. Both the PfLSA1 and Luc-gfp expression cassettes are integrated into the neutral 230p locus in chromosome 3.

Protein (function)

Phenotype

Additional remarks genetic modificationWe deleted the Pbs1 CDS and replaced it with a positive-negative selectable marker to create a Pbs1 deletion GIMO line (PbANKA-PfLSAP2+PbΔs1 GIMO; line 2374). In order to do this, we generated the pL1928 construct, based on the standard GIMO DNA construct pL0034. This construct contains a positive-negative (hdhfr::yfcu) SM cassette and was used to insert both the Pbs1 5′ and 3′ gene targeting regions (TRs). The linear pL1928 DNA construct was introduced into PbANKA-PfLSA1Pbuis4 parasites (line 2230 cl1) by using standard methods of transfection.
