Gene names
Name:SP23
OrganismTenebrio molitor (Yellow mealworm beetle)
Taxonomic identifier7067 [NCBI]
Taxonomic lineageEukaryotaMetazoaEcdysozoaArthropodaHexapodaInsectaPterygotaNeopteraEndopterygotaColeopteraPolyphagaCucujiformiaTenebrionidaeTenebrio

Protein attributes

Sequence length182 AA.
Sequence statusComplete.

General annotation (Comments)

Function

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.

Subcellular location

Secreted.

Tissue specificity

Spermatophore.

Developmental stage

Expressed at the beginning of the adult stage, about four days after the pupal peak of ecdysteroids.
