Gene Gene information from NCBI Gene database.
Entrez ID 643394
Gene name Serine peptidase inhibitor Kazal type 9
Gene symbol SPINK9
Synonyms (NCBI Gene)
LEKTI2
Chromosome 5
Chromosome location 5q32
Summary The protein encoded by this gene is a Kazal-type serine protease inhibitor that appears to specifically target kallikrein-related peptidase 5 (KLK5) in the palmo-plantar epidermis. KLK5 is an important initiator of skin desquamation, so the encoded protea
