We describe the isolation and embryonic pattern of expression of mouse Zfp462, a novel zinc finger protein gene. Zfp462 was isolated in a microarray-based search to identify genes differentially expressed in the late embryonic mouse cerebral cortex. The mouse Zfp462 deduced amino acid sequence is 2500 residues in length and contains 23 C(2)H(2)-type zinc finger motifs. Zfp462 shares low homology (30%) with non-vertebrate zinc finger proteins, suggesting that it is vertebrate-specific. However, domains found only in vertebrate-specific zinc finger proteins, such as the KRAB and SCAN domains, were not identified in Zfp462. We show that Zfp462 is expressed in the developing central nervous system, branchial arches, otic vesicles, sensory ganglia, somites and limbs. In the central nervous system, Zfp462 is expressed at the headfold stage and is later expressed in the developing forebrain, brainstem and spinal cord. Interestingly, beginning at E13.5, Zfp462 is expressed in a graded pattern in the mouse cerebral cortex. As predicted by the microarray analysis, Zfp462 is expressed at its highest levels in the caudal and medial cerebral cortex. Its expression in cortical layers is greatest in the marginal zone, the cortical plate and the subventricular zone. Zfp462 thus belongs to a growing family of molecular determinants that are expressed in a graded pattern in the developing cerebral cortex. This family includes transcription factor-encoding genes such as COUP-TF1, Emx2 and Pax6, which have been implicated in the process of cortical arealization.

Service providing functional analysis of proteins by classifying them into families and predicting domains and important sites. They combine protein signatures from a number of member databases into a single searchable resource, capitalizing on their individual strengths to produce a powerful integrated database and diagnostic tool. This integrated database of predictive protein signatures is used for the classification and automatic annotation of proteins and genomes. InterPro classifies sequences at superfamily, family and subfamily levels, predicting the occurrence of functional domains, repeats and important sites. InterPro adds in-depth annotation, including GO terms, to the protein signatures. You can access the data programmatically, via Web Services. The member databases use a number of approaches: # ProDom: provider of sequence-clusters built from UniProtKB using PSI-BLAST. # PROSITE patterns: provider of simple regular expressions. # PROSITE and HAMAP profiles: provide sequence matrices. # PRINTS provider of fingerprints, which are groups of aligned, un-weighted Position Specific Sequence Matrices (PSSMs). # PANTHER, PIRSF, Pfam, SMART, TIGRFAMs, Gene3D and SUPERFAMILY: are providers of hidden Markov models (HMMs). Your contributions are welcome. You are encouraged to use the ''''Add your annotation'''' button on InterPro entry pages to suggest updated or improved annotation for individual InterPro entries.
