Summary: Predicted to enable carbohydrate binding activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Involved in several processes, including motor neuron axon guidance; positive regulation of integrin-mediated signaling pathway; and striated muscle atrophy. Predicted to be part of collagen type IV trimer. Predicted to be active in collagen-containing extracellular matrix and extracellular space. Is expressed in several structures, including adult heart; embryonic/larval aorta; embryonic/larval dorsal vessel; embryonic/larval heart; and filzkorper. Used to study cardiomyopathy; dilated cardiomyopathy; mitochondrial myopathy; and myopathy. Human ortholog(s) of this gene implicated in primary angle-closure glaucoma. Orthologous to several human genes including COL15A1 (collagen type XV alpha 1 chain). [provided by Alliance of Genome Resources, Dec 2024]

Eater cooperates with Multiplexin to drive the formation of hematopoietic compartments.
Title: Eater cooperates with Multiplexin to drive the formation of hematopoietic compartments.
We further show that the SAGA deubiquitinase-activated gene Multiplexin (Mp) is required in glia for proper photoreceptor axon targeting. Mutations in the human ortholog of Mp, COL18A1, have been identified in a family with a SCA7-like progressive visual disorder, suggesting that defects in the expression of this gene in SCA7 patients could play a role in the retinal degeneration that is unique to this ataxia.
Title: Transcriptome Profiling Identifies Multiplexin as a Target of SAGA Deubiquitinase Activity in Glia Required for Precise Axon Guidance During Drosophila Visual Development.
The Endostatin domain of Multiplexin is specific for presynaptic homeostasis
Title: Endostatin is a trans-synaptic signal for homeostatic synaptic plasticity.
lack of Mp results in decreased diastolic capacity, leading to reduced heart contractility, as measured in live fly hearts.
Title: Multiplexin promotes heart but not aorta morphogenesis by polarized enhancement of slit/robo activity at the heart lumen.
multiplexin may be involved in establishing the Wingless signaling gradients in the Drosophila embryo
Title: Drosophila type XV/XVIII collagen, Mp, is involved in Wingless distribution.
