Protein

Spermatophorin SP23

Gene

SP23

Organism
Tenebrio molitor (Yellow mealworm beetle)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Structural protein of a layer within the wall of the spermatophore produced probably by cell type 4 of the bean-shaped gland (BAG). Fixation in the spermatophore seems to require covalent cross-linking of spermatophorins.
