Asimismo, se han identificado otros genes que pueden participar activamente en el desarrollo de este sindrome, entre los que se encuentra DLX3, FAM83H, MMP-20, KLK4 y WDR72 (14).
16) Several genes have been implicated in the development of amelogenesis imperfecta, including AMELX, ENAM, DLX3, FAM83H, MMP20, KLK4, and WDR72.
Among the topics are single nucleotide polymorphisms in the human kallikrein-related peptidase (KLK) locus and their implications in various diseases, molecular recognition properties of KLK on synthetic and endogenous substrates, KLK within the proteolytic web, the role of KLK4 in dental enamel formation, and physiological and pathophysiological roles of KLK in the central nervous system.

MONOCLONAL-POLYCLONAL ELISA CONFIGURATION, VERSION 1 (FOR KLK4, 12, AND 14)
KLK4 is up-regulated by androgens in prostate cancer cell lines (17) and by estrogens in endometrial cancer cell lines (16).
However, subsequent reverse transcription-PCR studies demonstrated that KLK4 mRNA is also expressed in other tissues, although at much lower concentrations than in the prostate (11,13 ).
An exception is one KLK4 isoform, which retains all of the residues of the catalytic triad but lacks the signal peptide and is thought to act intracellularly (21).
Previously, several other kallikreins, including KLK4, KLK5, KLK6, KLK7, KLK8, KLK9, KLK10, KLK11, KLK14, and KLK15, have been associated with various forms of malignancy and especially cancers of the ovary, breast, prostate, and testis [reviewed in Refs.
KLK4 is up-regulated by androgen in prostate and breast cancer cell lines (24) and by estrogen in endometrial cancer cell lines (25).
On the basis of the amino acid sequences, the closest relatives of KLK4 within the human kallikrein gene family are those that encode PSA (38% identity), the human stratum corneum chymotryptic enzyme (45% identity), and KLK6 (zyme/ neurosin/protease M; 38% identity) (6); the last and KLK10 are implicated in ovarian cancer (7, 8).
