Summary: A structural constituent of cytoskeleton. Involved in several processes, including male meiosis cytokinesis; nuclear pore localization; and regulation of actin filament polymerization. Located in lamin filament and spindle envelope. Colocalizes with nuclear envelope. Is expressed in several structures, including germline cell; gut section; oenocyte; somatic cell of ovariole; and somatic cell of testis. Used to study dilated cardiomyopathy 1A; familial partial lipodystrophy type 2; myopathy (multiple); and progeria. Human ortholog(s) of this gene implicated in several diseases, including brain disease (multiple); intrinsic cardiomyopathy (multiple); lipodystrophy (multiple); neuromuscular disease (multiple); and type 2 diabetes mellitus (multiple). Orthologous to human LMNA (lamin A/C); LMNB1 (lamin B1); and LMNB2 (lamin B2). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

Lamin C, the sole A-type lamin in Drosophila, contributes to the process of thorax closure in pupa.
Title: High expression of A-type lamin in the leading front is required for Drosophila thorax closure.
Human progeroid syndrome-modeled LamC mutations induced premature aging in adult flight muscles, including decreased levels of specific mitochondrial protein transcripts (RNA) and progressive mitochondrial degradation. They also induced the accelerated appearance of other phenotypes associated with aging.
Title: Lamin Mutations Accelerate Aging via Defective Export of Mitochondrial mRNAs through Nuclear Envelope Budding.
The critical function of A-type lamin C proteins in Drosophila musculature is to maintain proper function and morphology of tendon cells.
Title: Loss of Drosophila A-type lamin C initially causes tendon abnormality including disintegration of cytoskeleton and nuclear lamina in muscular defects.
