MGI Phenotype FUNCTION: This gene encodes a member of the kallikrein subfamily of serine proteases that are involved in diverse physiological functions such as skin desquamation, tooth enamel formation, seminal liquefaction, synaptic neural plasticity and brain function. The encoded preproprotein undergoes proteolytic cleavage of the activation peptide to generate the functional enzyme. Mice lacking the encoded protein exhibit impaired long-term potentiation and increased anxiety, as well as a hyperkeratosis phenotype. This gene is located in a cluster of several related kallikrein genes on chromosome 7. [provided by RefSeq, May 2016]
PHENOTYPE: Homozygotes for a null allele show aberrant synapses and neurons in the hippocampus CA1 field. Homozygotes for another null allele have normal LTP and spatial reference memory but show increased polyspiking in response to repetitive afferent stimulation and enhanced kainite-induced seizure activity.
