MGI Phenotype Strain: 3707077
FUNCTION: This gene encodes a member of the cadherin family of calcium-dependent glycoproteins that mediate cell adhesion and regulate many morphogenetic events during development. The encoded preproprotein is further processed to generate a mature protein. Mice lacking the encoded protein exhibit reduced behavioral responses to cold, but not thermal stimuli. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar proteolytic processing. Multiple distinct genes of the cadherin family, including this gene, are found on chromosome 8. [provided by RefSeq, Oct 2015]
PHENOTYPE: Mice homozygous for a null allele are viable, fertile and overtly normal but display abnormal CNS synaptic transmission, raise their tails in response to stress, and show reduced sensitivity to cutaneous cold stimuli. [provided by MGI curators]

Protein Function and Prediction

Cadherin 8 (Cdh8) is an integral membrane protein that mediates calcium-dependent cell-cell adhesion.  CDH8 has been implicated in both kidney morphogenesis as well as tumorigenesis in some types of renal cell carcinoma (1).  A knockout model demonstrated that Cdh8 is necessary to establish physiological coupling between cold-sensitive sensory neurons and their target dorsal horn neurons (2).  Furthermore, Cdh8 regulates mossy fiber fasciculation and targeting (3).

Expression/Localization

Northern blot analysis detected Cdh8 expression only in rat brain, with multiple transcripts present (4;5). Cdh8 can be detected in the kidney during early stages of kidney development (1).

Background

Cdh8tm1Mta/tm1Mta; MGI:3707077

B6.129P2-Cdh8tm1Mta

Mice homozygous for a null allele are viable, fertile and overtly normal but display abnormal CNS synaptic transmission, raise their tails in response to stress, and show reduced sensitivity to cutaneous cold stimuli (2).
