SSH is used by SSH to authenticate you on a remote computer. The ! mark is optional, it makes the primary key exportable and omits checking whether the key is authentication-capable ([CA]). What people call a "PGP key" is more of a certificate, containing ordinary RSA, ECDSA or other keypairs (the primary key and subkeys) along with the certificate's metadata.
