In the present paper, we give an operator with the help of a generalization of Boas-Buck type polynomials by means of Gamma function. We have approximation properties and moments. The rate of convergence is given by the Ditzian-Totik first order modulus of smoothness and the K-functional. Furthermore, we obtain the point-wise estimations for this operator.
