C. elegans ced-6 Functional Gene Editing Service

Service Overview Precision editing of CED-6 in a premier genetic model for cell death research

ced-6 encodes the C. elegans ortholog of mammalian GULP1, a key adapter that transduces the CED-1 / MEGF10 receptor signal to the actin-regulatory machinery during corpse engulfment. It sits at a critical node in the recognition branch, integrating receptor input to downstream effectors.

Because GULP1 is implicated in atherosclerosis and lipid-handling in mammals, ced-6 provides an in vivo model for CED-6 / GULP1 biology. CD BioSciences delivers knockout, knockin, and PTB-domain point mutants for functional dissection.

About the Target Gene: ced-6 Key biological and practical facts to inform your edit design

Gene symbol	ced-6 (Engulfment adaptor (GULP1 homolog))
Protein product	CED-6 — engulfment adapter (GULP1 ortholog)
Mammalian homolog	GULP1 (mammalian engulfment adapter)
Biological role	Adapter in the recognition branch of the engulfment pathway; transduces the CED-1 receptor signal to downstream actin regulators and the engulfment machinery.
Loss-of-function phenotype	Persistent cell corpses; engulfment-defective.
Why edit it	GULP1 / LRP1 biology; phagocytic signaling; atherosclerosis and lipid handling; cell-corpse recognition.
Recommended background	N2 (wild type); can be combined with ced-1, ced-7, or ced-10 mutants.
Representative allele	Standard knockout (ok / tm / gk series); n1813 is a canonical reference allele.

ced-6 at a glance: blocks engulfment of apoptotic corpses; persistent-cell-corpse phenotype easy to score. Editing ced-6 alone is a powerful way to dissect CED-6 function in vivo, with conserved relevance to human GULP1 biology.

Our ced-6 Editing Strategies Choose the allele that matches your experimental question

Gene Knockout

gRNA-guided Cas9 cutting with NHEJ repair to introduce frameshift indels, generating premature stop codons and null / strong-loss-of-function ced-6 alleles.

Knockin & Tagging

Homology-directed repair (HDR) inserts GFP / HA / FLAG or other tags at the ced-6 locus for endogenous expression and subcellular localization studies.

Point Mutation

Introduce specific amino-acid substitutions to dissect functional domains and separate catalytic from scaffolding roles of CED-6.

Conditional & Reporter Alleles

Build tissue-specific or inducible configurations and reporter lines for spatiotemporal analysis of CED-6 function.

Workflow of Our ced-6 Editing Service From sequence to validated strain in a streamlined pipeline

Strategy Design

Define target (knockout / knockin / point mutation), select gRNA(s) and HDR template, confirm against the latest genome build.

gRNA Synthesis

Design, validate, and synthesize high-specificity guide RNAs targeting the ced-6 locus.

Vector & Template Construction

Build Cas9 / gRNA delivery construct and, for knockin, the homology-arm repair template.

Microinjection

Perform gonadal microinjection of N2 animals with CRISPR components and co-CRISPR selection markers.

Screening & Verification

PCR, Sanger / sequencing, and phenotype confirmation to isolate edited animals and verify alleles.

Delivery & Report

Provide homozygous / balanced ced-6 strains plus a full genotype and methods report.

Frequently Asked Questions

What type of ced-6 allele will I get from a knockout project?

Standard knockout projects deliver a frameshift indel allele predicted to produce a premature stop and a loss-of-function phenotype. We confirm the edit by sequencing and, where relevant, by characteristic phenotype assays.

Can you add a GFP or epitope tag to endogenous ced-6?

Yes. Using HDR with a designed repair template, we can insert GFP, HA, or FLAG tags at the C- or N-terminus while preserving endogenous promoter and regulation.

How long does a typical ced-6 editing project take?

Timelines vary with editing type and validation needs, but our optimized pipeline and co-CRISPR selection typically shorten turnaround versus conventional approaches. Contact us with your design for a project-specific estimate.

How does CED-6 connect to CED-1?

The CED-1 intracellular tail binds directly to the CED-6 PTB domain. This is conserved in mammals between MEGF10 and GULP1. Mutating the CED-1 NPXY motif or the CED-6 PTB domain abolishes the interaction, providing a clean functional readout.
