The Anopheles gambiae Zinc finger CCCH-type with G patch domain-containing protein (AGAP002111) is a protein found in the Anopheles gambiae mosquito . Anopheles gambiae is a primary vector for malaria transmission in Africa. Understanding the proteins within this mosquito is crucial for developing strategies to combat malaria.
AGAP002111 is characterized as a DNA-binding transcription factor found in the nucleus of the cell . Its molecular function involves DNA-binding transcription factor activity . The protein contains a zinc finger CCCH-type domain and a G patch domain, structural motifs often associated with RNA binding and transcriptional regulation in other proteins.
Proteins have four levels of structure: primary, secondary, tertiary, and quaternary .
The peritrophic matrix (PM) in the mosquito midgut is a potential barrier for malaria transmission because the malaria parasite must cross it to complete its life cycle . Anopheles gambiae adult peritrophin 1 (Ag-Aper1) is a PM protein that binds to chitin, forming a network . Other midgut proteins also interact with Plasmodium falciparum, affecting parasite invasion . Some, such as AGAP006268, AGAP002848, AGAP006972, and AGAP002851, have a protective function against parasite invasion, while others like AGAP008138, FREP1, and HPX15 facilitate P. falciparum transmission to mosquitoes .
Anopheles gambiae devotes a significant portion of its protein-coding genes to structural cuticular proteins (CPs) . Some CPs, like CPLCG3 and CPLCG4, are implicated in insecticide resistance, while others, like CPF3, may play a role in desiccation tolerance .
The Anopheles gambiae genome contains a number of ATP-binding cassette protein genes . These genes encode proteins involved in various cellular processes . Gene duplication is evident in the Anopheles ABC genes, suggesting its active use as a mechanism to drive genetic variation in this gene group .

AGAP002111 is a 543 amino acid protein containing a CCCH-type zinc finger domain and a G-patch domain. The CCCH-type zinc finger domain is characterized by zinc ions coordinated by three cysteine residues and one histidine residue, typically involved in RNA binding. The G-patch domain is a glycine-rich sequence approximately 48 amino acids in length that functions in nucleic acid binding and protein-protein interactions .
Based on domain architecture and comparisons with similar proteins in other organisms, AGAP002111 likely functions in:
Nucleic acid binding, particularly RNA
RNA processing and regulation
Potential transcriptional regulation
AGAP002111 is located near but not within the proximal breakpoint of the 2Rj chromosomal inversion in Anopheles gambiae . This inversion is a 12.5 Mb chromosomal rearrangement fixed in the Bamako chromosomal form, which has distinctive breeding sites in rock pools beside the Niger River in Mali and Guinea .
Key details about this genomic context:
The gene is located in cytogenetic subdivision 10C, near the proximal breakpoint of 2Rj
The 2Rj inversion was formed by almost identical long inverted repeat modules at both breakpoints
These modules are 14.6 kb insertions consisting of 5.3 kb terminal inverted repeat arms separated by a 4 kb spacer
The inversion is estimated to be relatively recent (~0.4Ne generations)
This genomic location may have implications for the regulation and evolution of AGAP002111, particularly in populations carrying the 2Rj inversion.
When working with AGAP002111, it's important to distinguish it from unrelated proteins with similar acronyms:
The recombinant neurotoxic peptide AGAP described in some literature has analgesic and antitumor effects through inhibition of sodium channels in dorsal root ganglia neurons and is completely unrelated to the Anopheles gambiae protein AGAP002111 despite the similar acronym.
Based on recent advances in recombinant protein production in E. coli, the following approach is recommended for expressing AGAP002111:
Recent innovations suggest exploring antibiotic-free plasmid selection systems, which can reduce metabolic burden on cells and improve yield. The system described by Li et al. using calibrated T7 RNA polymerase expression levels may be particularly suitable for optimizing expression of potentially toxic recombinant proteins .
