Function

Required for male fertility. Plays a role in pollen tube guidance and successful gamete attachment. Essential for the fusion of gametes during double fertilization, where one male gamete fuses with the egg to produce a zygote, and another male gamete fuses with the central cell to produce the endosperm.

Biological Context

Subcellular Location: Endoplasmic reticulum membrane (Single-pass membrane protein); Cell membrane (Single-pass type I membrane protein)
Tissue Specificity: Expressed only in mature pollen, in the two sperm cells

Product Specifications

Recombinant Arabidopsis thaliana Protein HAPLESS 2 (HAP2) Protein is a recombinant protein from Arabidopsis thaliana (Mouse-ear cress), expressed in in vitro E.coli expression system, covering amino acids 25-705aa, with C-terminal 10xHis-tagged tag, molecular weight 81.0kDa, purity Greater than 95% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.
