This gene encodes a protein containing an N-terminal Kruppel-associated box-containing (KRAB) domain and 13 Kruppel-type C2H2 zinc finger domains. This gene resides on an area of chromosome X that has been implicated in nonsyndromic X-linked cognitive disability. Alternative splicing results in multiple transcript variants.
